Sodium Hydroxide Flakes

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. Dissolved under a written procedure, the flakes give alkali solutions for acid-base titration, neutralisation and pH work. The solid is corrosive and suits trained, supervised college and school laboratories. Science Lab Supplies sources this caustic reagent and sends it out of Ambala, India, against quotations from colleges, schools, tender contractors and distributors.
Specifications
Each property of the NaOH flakes appears as its own row in the table. In brief, sodium hydroxide has 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, and the batch label confirms physical form, grade and assay.

Applications and Experiments for Sodium Hydroxide Flakes
The flakes can be dissolved slowly, with stirring, in a Borosilicate Beaker to prepare sodium hydroxide solution, which is standardised against a standard acid and then used 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.
- Class 11 chemistry: finding the strength of a sodium hydroxide solution by titration against standard oxalic acid, with the burette held on a Burette Stand With Fisher Clamp.
- Class 10 science: neutralisation and the reaction of bases with acids.
- B.Sc. chemistry: volumetric analysis with NaOH as the titrant.
- Technician training: corrosive handling and safe dilution, wearing Safety Goggles, Polycarbonate, 12 pcs.
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. Titration benches needing caustic soda can be priced by message on the contact page or by listing the flakes in the enquiry cart; institutions buying by tender should start from 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, and its grade and assay are confirmed on the label.
Who supplies the Sodium Hydroxide Flakes?
A laboratory chemicals supplier in India, Science Lab Supplies, handles this alkali from Ambala. The quotation it issues spells out the grade and container size, and indicators or burettes can be added to it.
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, Alkalis and Safety Items
An alkali titration also needs an indicator to show the end point, a standard acid to fix the concentration and a burette to deliver the solution. The items below complete that set-up, add two more bases for comparison and protect the hands of whoever dispenses the flakes; all can be quoted together.

- Calcium Hydroxide — Ca(OH)2 alkali for limewater and carbon dioxide tests.
- Phenolphthalein Solution Indicator — turns pink in alkaline conditions at the titration end point.
- Methyl Orange — indicator with a transition range of about pH 3.1–4.4.
- Oxalic Acid — ethanedioic acid, used where a standardisation reagent is specified.
