Calcium Hydroxide
Calcium Hydroxide (Product Code: SCL362/081) is an alkaline calcium compound, also called slaked lime, used to prepare limewater for the carbon dioxide test and for base and neutralisation experiments in school and college laboratories. Biology and chemistry teachers buy it as a 100 g pack of analytical reagent grade, delivered with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India that also provides the glassware needed to use it.

What Is Calcium Hydroxide Used For?
Its most familiar classroom use is limewater: shake a little calcium hydroxide with distilled water, let the excess settle and filter off the clear solution. When carbon dioxide from breath, a burning candle or an acid–carbonate reaction is bubbled through it, the limewater turns milky as insoluble calcium carbonate forms. The same test appears in biology respiration practicals and in chemistry gas-identification lessons.
Teachers also use calcium hydroxide to demonstrate neutralisation and to show how a sparingly soluble base behaves in water. Wear eye protection while weighing the solid, because it is caustic, and keep the pack closed so it does not slowly absorb carbon dioxide from the air. Stock it next to the rest of your school chemistry lab equipment so limewater can be made fresh before each class.
What to Specify When Ordering

Frequently Asked Questions
What is Calcium Hydroxide used for in school labs?
Calcium Hydroxide (SCL362/081) is mainly used to prepare limewater, the classic test for carbon dioxide, and for simple neutralisation and base experiments. Students watch the clear limewater turn milky when carbon dioxide passes through it.
What quantity does one pack of Calcium Hydroxide contain?
One pack of Calcium Hydroxide (SCL362/081) contains 100 g of analytical reagent grade material. Only a small amount is needed for each batch of limewater, so order extra packs mainly when several lab rooms share the stock.
Is an MSDS provided with the Calcium Hydroxide?
Yes, Calcium Hydroxide from ScienceLab is supplied with an MSDS. It sets out the hazards of this caustic alkali, the protective equipment to wear, first-aid steps and safe storage, and belongs in the lab’s chemical safety file.
How long does Calcium Hydroxide stay usable?
How long Calcium Hydroxide stays usable depends on the chemical, its grade and storage conditions, and an open container slowly picks up carbon dioxide from air. Ask us for the expiry date of the batch you are quoted, and keep the pack sealed.
Who is the supplier of this Calcium Hydroxide?
Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, supplies this Calcium Hydroxide. It is a sourced analytical reagent, offered alongside laboratory apparatus to schools, colleges, dealers and importers in India and international markets.
Can Calcium Hydroxide be supplied in bulk or for export?
Yes, Calcium Hydroxide can be quoted in multiple 100 g packs for institutions, dealers and export orders. Send the quantity, destination and any document needs through our contact page so we can confirm availability and shipping.
