Sodium Hydroxide
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.

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.
Supplier
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, supplies Sodium Hydroxide as part of a broad list of acids, alkalis and indicators sourced for teaching and testing laboratories. Buyers in India and international markets, including dealers and importers, can have it quoted together with burettes, pipettes and flasks. Company information is on the ScienceLab profile.

Frequently Asked Questions
What is Sodium Hydroxide SCI-440/133 used for?
Sodium Hydroxide SCI-440/133 is used as the standard alkali in acid-base titrations, to identify metal and ammonium ions in salt analysis and to make soap from fats. As an analytical reagent grade chemical, it suits quantitative school and college practicals.
How much Sodium Hydroxide is in each pack?
Each pack of Sodium Hydroxide SCI-440/133 contains 500 g of analytical reagent grade material with an MSDS. Give us the number of packs your laboratories need; the same quotation can also cover acids, indicators and titration glassware.
Why must sodium hydroxide solutions be standardised?
Sodium Hydroxide absorbs moisture and carbon dioxide from the air, so the mass weighed out does not give an exact concentration. Standardise solutions made from Sodium Hydroxide SCI-440/133 against a primary standard such as oxalic acid before accurate titrations.
Is this Sodium Hydroxide in pellet or flake form?
The listing for Sodium Hydroxide SCI-440/133 gives its analytical reagent grade and 500 g pack but does not state whether it is pellets, flakes or powder. Contact us if your procedure needs a particular form, and we will confirm the batch.
What is the shelf life of Sodium Hydroxide SCI-440/133?
The shelf life of Sodium Hydroxide SCI-440/133 depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep it in a closed container in a dry place so it stays free-flowing.
Is Sodium Hydroxide dangerous to handle?
Sodium Hydroxide is strongly corrosive and can cause serious eye and skin burns, even when a dilute solution splashes into the eye. Handle Sodium Hydroxide SCI-440/133 with goggles and gloves, and keep the supplied MSDS available for first aid and spills.
Who supplies Sodium Hydroxide SCI-440/133?
Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India supplies Sodium Hydroxide SCI-440/133 to schools, colleges, testing laboratories, dealers and importers in India and international markets, and can add it to wider orders for titration and salt-analysis equipment.
