What Is Sodium Chromate Used For?
The chromate–dichromate system is a favourite illustration of Le Chatelier's principle: adding dilute acid to yellow sodium chromate solution turns it orange as dichromate forms, and adding sodium hydroxide reverses the change. Students can repeat the shift several times in one test tube and link each colour to the direction in which the equilibrium has moved.
Sodium chromate solution also precipitates yellow barium chromate and yellow lead chromate, giving quick tests for these ions, and it is discussed as a corrosion inhibitor and oxidising agent in industrial chemistry lessons. It is hygroscopic, so reseal the pack promptly. As a chromium(VI) compound it is toxic, carcinogenic and an oxidiser: keep it away from combustibles, wear gloves and goggles, and collect all residues for hazardous-waste disposal.
Supplier
ScienceLab, the name under which Jain Scientific Equipments Private Limited of Ambala trades, supplies Sodium Chromate to chemistry departments, training colleges and laboratory dealers in India and international markets. Because the two chromate salts are close alternatives, buyers can ask for sodium and potassium chromate to be quoted side by side before deciding. The ScienceLab profile explains more about the company.
Related Laboratory Equipment
Reagents and apparatus for chromate–dichromate and precipitation experiments:
- Sodium Dichromate — the orange dichromate salt formed on acidification.
- Sodium Hydroxide — shifts the equilibrium back to yellow chromate.
- Barium Chloride — forms a yellow barium chromate precipitate.
- Potassium Chromate — the potassium salt, usually chosen as the Mohr titration indicator.
- Test Tube Racks — hold the tubes during the equilibrium demonstration.

Frequently Asked Questions
How does Sodium Chromate show Le Chatelier's principle?
Sodium Chromate solution is yellow; adding dilute acid turns it orange as dichromate forms, and adding alkali turns it yellow again. Each colour change shows the chromate–dichromate equilibrium shifting in response to added hydrogen or hydroxide ions.
Should I choose Sodium Chromate or potassium chromate?
Sodium Chromate is more soluble and absorbs moisture more readily, which suits concentrated solutions and equilibrium demonstrations, while potassium chromate is usually chosen as the Mohr titration indicator. Both are chromium(VI) salts that need the same careful handling.
What does Sodium Chromate SCI-611/266 contain?
Sodium Chromate SCI-611/266 is a 100 g pack of analytical reagent grade sodium chromate with an MSDS. Acids, alkalis and glassware for the demonstrations are separate catalogue items that can be quoted together.
What safety precautions does Sodium Chromate need?
Sodium Chromate is a toxic, carcinogenic chromium(VI) compound and an oxidiser. Handle it with gloves and goggles under supervision, keep it away from flammable materials, avoid dust, and follow the disposal steps in the MSDS supplied with the pack.
How should Sodium Chromate be stored?
Keep Sodium Chromate tightly closed in a dry, locked cabinet, separate from reducing agents and combustibles, because it absorbs moisture and is a strong oxidiser. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Who supplies Sodium Chromate SCI-611/266?

| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Xylene Used For?
In histology and pathology teaching, xylene is the clearing agent that follows the graded alcohol series: it displaces ethanol from dehydrated tissue so that molten paraffin wax can infiltrate it. After sectioning, slides pass through xylene again to dissolve the wax before staining, and a final xylene bath prepares stained sections for a resin-based mountant and cover slip.
Chemistry departments use xylene as a non-polar solvent in extraction and solubility practicals, and microscope users apply a trace on lens tissue to lift dried immersion oil after checking the objective maker's cleaning advice. Xylene is flammable and its vapour is harmful, so dispense it in a fume cupboard, keep the bottle capped away from flames and follow the MSDS for disposal.
Supplier
Xylene is a sourced laboratory chemical: Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies it with its MSDS to schools, colleges, teaching laboratories and dealers alongside the rest of its chemistry range. Because xylene is a flammable liquid, tell us the delivery address early so that we can advise on packing and transport within India and to international markets. Learn more about the company on the ScienceLab company profile.

| Product code | SCI-615/268 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Blue Litmus Paper Used For?
Blue litmus is the quick first check in acid–base topics: students dip a strip, or touch it with a drop carried on a glass rod, into vinegar, lemon juice, dilute hydrochloric acid or soap solution and record which samples turn it red. In salt analysis, a strip moistened with distilled water and held at the mouth of a test tube helps confirm acidic gases such as hydrogen chloride or sulfur dioxide.
Because the paper only reports “acid or not”, pair it with red litmus to separate bases from neutral substances, and move to universal indicator when an approximate pH value is needed. Handle strips with clean, dry fingers or forceps, avoid touching the test area, and keep the container closed so that laboratory fumes do not change the colour before use.
Supplier
Jain Scientific Equipments Private Limited trades as ScienceLab and supplies Litmus Paper (Type Blue) as a sourced consumable, often packed with chemicals and glassware in orders for schools, colleges and distributors. Institutional buyers completing vendor registration can record the supplying company's GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. Company background is available on the ScienceLab profile.

Frequently Asked Questions
What does Litmus Paper (Type Blue) show?
Litmus Paper (Type Blue) shows whether a substance is acidic: acids turn the blue paper red, while bases and neutral substances cause no colour change. It cannot tell a base from a neutral liquid, so red litmus is used for that second check.
What is the difference between blue and red litmus paper?
Blue litmus paper detects acids by turning red, whereas red litmus paper detects bases by turning blue. Using Litmus Paper (Type Blue) together with Litmus Paper (Type Red) lets students sort samples into acidic, basic and neutral groups.
Can Litmus Paper (Type Blue) test gases?
Yes, Litmus Paper (Type Blue) can test acidic gases if the strip is first moistened with distilled water, because the gas must dissolve to act on the dye. Hold the damp strip at the mouth of the test tube rather than dipping it into the liquid.
How should Litmus Paper (Type Blue) be stored?
Keep Litmus Paper (Type Blue) in its closed container in a dry cupboard, away from acid and ammonia fumes and direct sunlight. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

What Is Red Litmus Paper Used For?
Red litmus is the standard way to confirm that something is alkaline. Classes test soap solution, baking soda solution, lime water and dilute sodium hydroxide, and in the ammonium-ion test a damp red strip held over a warmed mixture of an ammonium salt and alkali turns blue as ammonia is given off.
Because acids and neutral liquids both leave it red, red litmus works as a pair with blue litmus: a sample that changes neither paper is neutral. Use a fresh strip for every sample, place a drop rather than dipping when the liquid is concentrated, and compare the result with an unused strip in daylight. Needing no preparation, it is a staple litmus paper for school labs in India and abroad.
Supplier
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which sources Litmus Paper (Type Red) and supplies it with its wider range of chemistry consumables to schools, colleges, laboratories and dealers. Combining red and blue litmus, indicators and reagents in one enquiry keeps ordering simple for a practical season. See the ScienceLab profile for more about the company.
Related Laboratory Equipment
Items that go with red litmus in alkali and gas tests:
- Litmus Paper (Type Blue) — the acid-detecting partner paper.
- Sodium Hydroxide — a typical alkali for demonstrating the blue change.
- Ammonium Hydroxide (ammonia water) — gives off ammonia vapour for gas-test practice.
- Dropper — places single drops of a sample on the strip.
- Test Tube Holder — grips a warm tube while a damp strip is tested at its mouth.
More indicators and apparatus are listed in the Laboratory Equipment category.
Frequently Asked Questions
What does Litmus Paper (Type Red) detect?
Litmus Paper (Type Red) detects bases: an alkaline solution, or a basic gas on a damp strip, turns the red paper blue. Acids and neutral substances leave it red, so it is used with blue litmus to tell those two groups apart.
How is Litmus Paper (Type Red) used in the ammonium ion test?
In the ammonium ion test, a strip of Litmus Paper (Type Red) is moistened with distilled water and held at the mouth of a tube in which an ammonium salt is warmed with alkali. Ammonia released by the reaction turns the strip blue.
Why does Litmus Paper (Type Red) stay red in water?
Litmus Paper (Type Red) stays red in pure water because water is neutral and only a base changes the colour to blue. If a water sample turns it blue, the sample contains dissolved alkaline substances that are worth investigating further.
How should Litmus Paper (Type Red) be stored?
Store Litmus Paper (Type Red) in its closed container, in a dry place away from ammonia, acid vapours and strong light. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

| Product code | SCI-619/270 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is 120 mm Filter Paper Used For?
In the classroom the circle is folded into a cone, seated in a funnel and wetted with a little distilled water so that it clings to the glass. Students then separate sand from salt water, collect a precipitate formed in a reaction, or clear a cloudy extract before testing it. Pour down a glass rod and keep the liquid level below the paper's rim so that nothing bypasses the filter.
A fluted fold speeds filtration when only the filtrate matters, while a plain cone is easier to scrape when the solid residue is what you need. Outside schools, papers of this kind clarify samples in food and agricultural testing and support air pollution monitoring and gas detection work. Check that the folded circle sits just below the rim of the funnel you plan to use.

| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Chromatography Paper Used For?
For paper chromatography in school, students draw a pencil baseline a short distance above the lower edge, spot the sample on it with a capillary tube and stand the sheet in a container whose solvent sits below the line. As the solvent climbs, each dye travels a different distance, and the class calculates Rf values by dividing the distance moved by a spot by the distance moved by the solvent front.
Typical experiments include separating black marker ink, checking the colours in sweets or food colouring, and separating chlorophyll and carotenoid pigments from leaf extracts with a suitable solvent. Handle the sheet by its edges, mark it only in pencil and let it dry flat before measuring. Several spots can be run side by side on one sheet so that samples are compared under identical conditions.

What Is Magnesium Powder Used For?
Its large surface area makes magnesium powder react far faster than ribbon, which is exactly what rate-of-reaction lessons need: students add a small weighed portion to dilute hydrochloric acid and compare the fizzing, temperature rise and volume of hydrogen collected with results from strip. In displacement practicals, powder stirred into copper sulfate solution becomes coated with copper while the blue colour fades.
College organic labs also use magnesium metal to prepare Grignard reagents under strictly dry conditions. Treat the powder as a flammable solid: weigh out only what the lesson needs, keep it away from flames, water and oxidisers, and never tip unused powder back into the pack. A magnesium fire must not be tackled with water, so keep dry sand to hand and follow the MSDS.

What Is Magnesium Ribbon Used For?
The classic use is the combustion demonstration: a short piece held in crucible tongs and lit in a Bunsen flame burns with an intensely bright white light and leaves white magnesium oxide. In the quantitative version, students heat a coiled, weighed length in a lidded crucible, lifting the lid briefly to admit air, then reweigh the product to show the gain in mass and work out the oxide's empirical formula.
Because every piece has the same width and thickness, cutting equal lengths gives reproducible samples for comparing how quickly magnesium reacts with acids of different concentrations or temperatures. Rub each piece with sandpaper first to remove the dull oxide film, avoid looking directly at burning magnesium, and keep the coil in a sealed container so that the surface stays bright.
