Product Code : SCL-LC-12293
Sodium Hydroxide Flakes (SKU SCL-LC-12293) are solid NaOH, the strong alkali also known as caustic soda or lye. Chemistry laboratories dissolve the flakes to make alkali solutions for acid-base titration, neutralisation and pH work. The solid is corrosive and meant for trained, supervised use. Science Lab Supplies supplies the flakes from Ambala, India, to colleges, schools, training institutes, tender contractors and distributors.
Specifications
Sodium hydroxide has the formula NaOH, CAS number 1310-73-2 and a molecular weight of 39.9971 g/mol. It is a strongly corrosive solid that gives off heat as it dissolves in water. The name indicates flakes; physical form, grade, assay and pack size are confirmed on the label and the quotation.

Applications and Experiments for Sodium Hydroxide Flakes
Laboratories dissolve the flakes to prepare sodium hydroxide solutions, standardise them against a standard acid, and then use them as the alkali in titrations, neutralisation experiments and pH demonstrations. Making the solution also shows, under close supervision, how much heat a strong base releases when it dissolves.
- Class 11 chemistry: finding the strength of a sodium hydroxide solution by titration against standard oxalic acid.
- Class 10 science: neutralisation and the reaction of bases with acids.
- B.Sc. chemistry: volumetric analysis with NaOH as the titrant.
Standard Scope of Supply
You receive the flakes in a closed container in the pack size quoted, labelled with batch and hazard details and dispatched with the Safety Data Sheet and transport documents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
We can quote one container for a small stockroom or a larger supply for several practical groups; each quotation sets out the packing, delivery time and price for that quantity. Indicators, standard acids and other titration apparatus can be listed on the same enquiry.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. For a quotation, write to us through the contact page or add the flakes to the enquiry cart; tender buyers will find the process on the lab tender page.
Frequently Asked Questions
Are sodium hydroxide flakes hazardous?
Yes. They are strongly corrosive to skin and eyes and release heat when dissolved. Only trained staff should dispense them, wearing chemical-resistant gloves and eye or face protection; keep them apart from acids, aluminium, tin and zinc, and never issue them to students unsupervised.
Is sodium hydroxide the same as caustic soda?
Yes. Sodium hydroxide, NaOH, is commonly called caustic soda or lye. This is the laboratory flake form, not a household or drain-cleaning product.
Who supplies the Sodium Hydroxide Flakes?
Science Lab Supplies, a laboratory chemicals supplier in India, dispatches them from Ambala to colleges, schools and distributors, and the quotation names the grade and pack size on offer.
Why must the container be kept tightly closed?
The flakes absorb moisture and carbon dioxide from the air, which cakes the solid and alters the strength of its solutions. Close it straight after weighing and store it cool, dry and ventilated.
Related Titration Reagents and Alkalis
An alkali titration also needs an indicator to show the end point, and often a standard acid to fix the concentration. The four reagents below from the Lab Chemicals range complete that set-up or offer a second strong base, and they can be quoted together.
- Potassium Hydroxide Flakes — the potassium strong alkali, also in flake form, for titration and pH work.
- Phenolphthalein Solution Indicator — gives a pink alkaline end point in acid-base titrations.
- Methyl Orange — titration indicator often compared with phenolphthalein in class.
- Oxalic Acid — organic acid for titration and standardisation work where the method specifies it.
