Phenolphthalein (Product Code: SCI-412/127) is an analytical reagent grade acid-base indicator used to mark the end point of titrations and to show whether a solution is alkaline in school, college and testing laboratories. It stays colourless in acidic and neutral solutions and turns pink in alkaline ones, making it the core reagent of any acid base indicator kit; it is packed as a 250 ml quantity with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for titration benches in teaching and testing labs.

Specifications

What Is Phenolphthalein Used For?

Phenolphthalein is the indicator of choice when a strong alkali such as sodium hydroxide is titrated against an acid: a few drops in the conical flask stay colourless until the final drop of alkali tips the solution to a permanent pale pink. It is especially suited to weak acid and strong base titrations, such as ethanoic acid against sodium hydroxide, where methyl orange would change colour too early. Teachers also use it in “invisible ink” demonstrations and to show that limewater and soap solutions are alkaline.

Add only two or three drops per titration, because the indicator is itself a weak acid and an excess can shift the end point slightly. Keep the bottle closed, away from strong light and alkalis, and file the MSDS with your chemical register so every user has the handling information.

Supplier

Phenolphthalein is sourced by Jain Scientific Equipments Private Limited, whose trading name is ScienceLab, and supplied with the other indicators, acids and alkalis used in titration work. Schools, colleges, dealers and importers in India and international markets can combine it with burettes and flasks in one order. Learn about the company on the ScienceLab profile.

Red Phosphorus (Product Code: SCI-430/128) is an analytical reagent grade allotrope of the element phosphorus used to demonstrate allotropy and the combustion of non-metals in school and college chemistry laboratories. It comes as a 50 g pack with an MSDS, and demonstrations typically use only small portions at a time. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to chemistry departments that source their reagents from one laboratory chemicals supplier in India.

Specifications

What Is Red Phosphorus Used For?

Red phosphorus lets teachers show allotropy: it is the same element as white phosphorus but far more stable in air, which is why the red form is the one kept in teaching labs and used on the striking strip of safety match boxes. In the combustion-of-non-metals demonstration, a small amount burned on a deflagrating spoon in a gas jar of oxygen produces dense white smoke of phosphorus oxide. Shaken with a little water, the oxide gives an acidic solution that turns blue litmus red.

Red phosphorus is a flammable solid that can ignite through friction, especially when mixed with oxidising agents such as chlorates, so never grind it or store it near oxidisers. Carry out demonstrations in a fume cupboard, keep the container tightly closed in a cool, dry place, and have dry sand ready for smothering a small fire. Some countries control the sale and transport of red phosphorus, so check local regulations before ordering.

Supplier

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, sources Red Phosphorus for teaching laboratories and supplies it with an MSDS. Institutions, dealers and importers in India and international markets should mention the intended use and destination in their enquiry, as flammable solids are subject to transport rules.

It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, one of the school science lab equipment suppliers in India.

Specifications

What Is Reduced Iron Powder Used For?

The classic practical heats a mixture of iron powder and sulfur: before heating, a magnet pulls the iron out of the yellow mixture, but after the glowing reaction the black iron(II) sulfide is no longer drawn out by the magnet in the same way, showing the difference between a mixture and a compound. Iron powder stirred into blue copper sulfate solution becomes coated with pink copper as the solution fades to pale green, a clear displacement reaction.

Students also sprinkle a pinch into a Bunsen flame to see bright sparks, showing how a large surface area speeds up combustion, and set up rusting tests comparing iron in dry air, boiled water and moist air. Keep the container tightly closed, as fine iron slowly oxidises in damp air, and wear eye protection whenever it is heated.

Supplier

Powdered Iron (reduced) is one of the reagent metals that Jain Scientific Equipments Private Limited, trading as ScienceLab, sources and supplies for chemistry teaching.

Ammonium Hydroxide (ammonia water) (Product Code: SCI-429/130) is an analytical reagent grade solution of ammonia in water used as a weak alkali for qualitative salt analysis, precipitation tests and ammonia diffusion demonstrations in school and college chemistry laboratories. It is supplied in a 500 ml bottle with an MSDS, and its pungent vapour means it should be opened in a fume cupboard. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a supplier of lab chemicals in India.

Specifications

What Is Ammonium Hydroxide Used For?

In qualitative analysis, dilute ammonium hydroxide added drop by drop to a metal salt solution identifies cations by their precipitates: copper ions give a pale blue precipitate that dissolves in excess to a deep blue solution, while iron(III) ions give a rust-brown one. It also neutralises acids gently, which makes it useful for adjusting pH and for weak-base titrations with methyl orange as the indicator.

For a memorable diffusion demonstration, cotton wool soaked in ammonia water and in hydrochloric acid is placed at opposite ends of a glass tube; a white ring of ammonium chloride forms nearer the acid end, because ammonia molecules are lighter and move faster. Open the bottle slowly, as gas pressure can build up in warm weather, and keep it in a chemistry reagent cabinet away from acids and oxidisers.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which sources Ammonium Hydroxide (ammonia water) and supplies it with other qualitative-analysis reagents to schools, colleges and laboratories.

Calcium Hydroxide 200g (Product Code: SCI-417/131) is an analytical reagent grade white alkaline solid, also known as slaked lime, used to prepare limewater for the carbon dioxide test and to study neutralisation in school and college laboratories. As the name indicates, it is packed as 200 g with an MSDS, and because it dissolves only slightly, a small portion makes plenty of limewater. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

Specifications

What Is Calcium Hydroxide Used For?

Shaking calcium hydroxide with distilled water and filtering off the excess gives limewater, the standard test for carbon dioxide: when the gas is bubbled through, the clear solution turns milky as insoluble calcium carbonate forms. Biology classes use the same limewater to compare inhaled and exhaled air, and chemistry students use it to identify the gas released when acids react with carbonates.

Calcium hydroxide also shows how slaked lime neutralises acidic soil and water, and it links calcium oxide, calcium hydroxide and calcium carbonate in the limestone cycle. It is an alkali that irritates eyes and skin, so wear goggles when weighing it, and keep the container sealed because air slowly converts it to calcium carbonate.

Supplier

Potassium Hydroxide (Product Code: SCI-435/132) is an analytical reagent grade strong alkali, also called caustic potash, used to absorb carbon dioxide in respiration and photosynthesis experiments, make soft soap and prepare alkaline solutions in school and college laboratories. It is packed in 200 g quantities with an MSDS and must be kept sealed, because it draws moisture and carbon dioxide from the air. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which is also a biology lab equipment supplier in India.

Specifications

What Is Potassium Hydroxide Used For?

Potassium hydroxide solution readily absorbs carbon dioxide, so biology practicals place it inside a respirometer to remove the carbon dioxide released by germinating seeds, letting a coloured liquid index measure oxygen uptake. It is also sealed in a flask with a leaf to show that a leaf deprived of carbon dioxide makes no starch. In chemistry, it saponifies oils and fats to give soft potassium soap, and its solutions serve as strong-alkali titrants and electrolytes.

Dissolving the solid releases a lot of heat and can spatter, so add it slowly to cold water in a borosilicate beaker while stirring, wearing goggles and gloves. Weigh it quickly and replace the lid at once, since it turns damp on standing, and store it away from acids and from metals such as aluminium and zinc.

Sodium Hydroxide (Product Code: SCI-440/133) is an analytical reagent grade strong alkali, commonly called caustic soda, used as the standard base in acid-base titrations, for identifying metal and ammonium ions and for soap-making practicals in school, college and testing laboratories. It is packed as a 500 g quantity with an MSDS, a convenient stock size for departments that make up their own alkali solutions. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier for teaching labs.

Specifications

What Is Sodium Hydroxide Used For?

In volumetric analysis, sodium hydroxide solution is titrated against hydrochloric, sulfuric or ethanoic acid with phenolphthalein as the indicator. Because the solid absorbs moisture and carbon dioxide, a freshly made solution is standardised against a primary standard such as oxalic acid before accurate work. Colleges also use it to saponify fats into hard soap.

In qualitative analysis, sodium hydroxide solution identifies metal ions by the colour of their hydroxide precipitates, such as blue for copper(II) and red-brown for iron(III), and it releases ammonia when warmed with an ammonium salt. Dissolving the solid produces strong heat, so add it gradually to cold water while stirring, wear goggles and gloves, and keep the container firmly closed between uses.
