Sodium Hydroxide 500 g
Sodium Hydroxide 500 g (Product Code: SCI-536/232) is analytical reagent grade caustic soda, a strong alkali used to prepare standard solutions for acid-base titration and to identify metal ions by their hydroxide precipitates in school and college laboratories. The larger 500 g pack, supplied with an MSDS, suits stockrooms that make up alkali for many practical groups. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Sodium Hydroxide Used For?
Sodium hydroxide solution is the standard alkali of volumetric analysis. Because the solid absorbs water and carbon dioxide from air, its solution is first standardised against a primary standard such as oxalic acid, then titrated against unknown acids using phenolphthalein. This sequence is the core exercise of any titration kit used in schools and colleges in India.
In qualitative analysis, a few drops of dilute sodium hydroxide identify cations by colour: blue copper(II) hydroxide, dirty-green iron(II) hydroxide, red-brown iron(III) hydroxide and white precipitates with zinc, aluminium and calcium, where the zinc and aluminium precipitates redissolve in excess. It is also used to saponify fats into hard soap. The solid is highly corrosive and heats up strongly as it dissolves, so wear goggles and gloves, store solutions in polyethylene bottles and use burettes with PTFE stopcocks, since alkali can seize glass keys.
Supplier
Sodium Hydroxide 500 g is supplied by Jain Scientific Equipments Private Limited, the company that trades as ScienceLab in Ambala, Haryana, for laboratories that buy alkali in larger packs together with titration glassware and indicators. The ScienceLab profile page has more about the company.
Related Laboratory Equipment
Titration and cation-test benches stocked with Sodium Hydroxide 500 g also use:
- Oxalic Acid — primary standard for standardising sodium hydroxide solution.
- Burette, Class-B, with PTFE Key Stopcock — resists seizing when alkali is dispensed.
- Phenolphthalein 250 ml — end-point indicator for sodium hydroxide titrations.
- Bottle, Polyethylene, Widemouthed — alkali-safe storage for prepared solutions.
- Iron Chloride (III) — gives a red-brown hydroxide precipitate in cation tests.
Other acids and alkalis are in the Laboratory Equipment category.
Frequently Asked Questions
What is Sodium Hydroxide 500 g used for?
Sodium Hydroxide 500 g is used to prepare standard alkali for acid-base titrations, to identify metal cations by their coloured hydroxide precipitates, to make soap by saponification and to demonstrate neutralisation. It is analytical reagent grade caustic soda supplied with an MSDS.
Why does sodium hydroxide solution need standardising?
Solid Sodium Hydroxide 500 g absorbs moisture and carbon dioxide from air, so a weighed mass never gives an exact concentration. Its solution is therefore titrated against a primary standard such as oxalic acid, and the measured concentration is used in later titrations.
How should Sodium Hydroxide 500 g be stored?
Store Sodium Hydroxide 500 g tightly closed in a dry cabinet away from acids and aluminium. Keep prepared solutions in polyethylene or rubber-stoppered bottles, because concentrated alkali attacks glass and can cement ground-glass stoppers in place.
What should be done if sodium hydroxide splashes on skin or eyes?
Sodium Hydroxide 500 g is highly corrosive and can cause severe eye damage. Rinse any splash immediately with plenty of running water for several minutes, remove contaminated clothing and seek medical help, following the first-aid section of the MSDS supplied with the pack.
What is the shelf life of Sodium Hydroxide 500 g?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Sodium Hydroxide 500 g. Ask us for the expiry date of the batch you are quoted, and reseal the container quickly after each use.
Can Sodium Hydroxide 500 g be supplied for several laboratories?
Yes. Sodium Hydroxide 500 g can be quoted in multiples of the 500 g pack for schools, colleges and dealers in India and international markets. Send the quantity and destination to Jain Scientific Equipments Pvt Ltd (ScienceLab) through the contact page.
