Product Code : SCL-LC-12294
Calcium Hydroxide (SKU SCL-LC-12294), also known as slaked lime or hydrated lime, is an alkaline reagent for making limewater, the classic test for carbon dioxide. It also serves lessons on bases, neutralisation and calcium compounds in school and college chemistry. Science Lab Supplies quotes and dispatches this reagent from Ambala, India, for schools, colleges, tender contractors and distributors.
Specifications
Each property of this slaked-lime reagent has its own row below. In summary, the compound is Ca(OH)2 with CAS number 1305-62-0 and a molecular weight of about 74.1 g/mol; its alkaline dust can irritate or damage the eyes, skin and airways, and grade, assay and pack size are fixed on the quotation.

Applications and Experiments for Calcium Hydroxide
Its main job is limewater: when carbon dioxide bubbles through the clear solution, insoluble calcium carbonate forms and the liquid turns milky. The same reagent shows that a base neutralises an acid and introduces the chemistry of calcium and other alkaline earth compounds.
- Class 10 science: testing the gas from acids and carbonates, with limewater held in Test Tubes.
- Biology practicals: showing that exhaled air contains more carbon dioxide, using limewater in a Borosilicate Conical Flask.
- Class 11 chemistry: properties of calcium compounds in the s-block elements unit.
- Qualitative inorganic analysis involving calcium compounds.
Clear limewater keeps longer in a stoppered vessel such as the Glass Reagent Bottle With Screw Cap.
Standard Scope of Supply
The order is one pack of calcium hydroxide in the quantity quoted, with a label giving batch and hazard details, the Safety Data Sheet and the 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
A quotation can cover one pack for a single lab or bulk packs for many schools, and it states the packing, delivery time and price for exactly what you request. Glassware for limewater tests and other school chemistry lab equipment in India can be added to it.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Send the quantity of slaked lime you need via the contact page, or combine it with glassware in the enquiry cart; schemes bought by tender go through the lab tender page.
Frequently Asked Questions
How is limewater made from calcium hydroxide?
Stir a small amount into water, let the undissolved solid settle and filter off the clear, saturated solution. Keep it stoppered, because carbon dioxide from the air slowly turns it milky.
Is calcium hydroxide the same as slaked lime?
Yes. Slaked lime, hydrated lime, calcium hydrate and caustic lime are all names for Ca(OH)2. Check the label for the grade before using it in a practical.
Is calcium hydroxide hazardous?
Yes, it needs care. The alkaline dust can irritate or damage the eyes, skin and respiratory tract, so use eye protection, gloves and dust control, and let trained staff supervise weighing and mixing.
Who supplies the Calcium Hydroxide?
Orders for this reagent are handled by Science Lab Supplies in Ambala, India. Every quotation names the grade and pack size of the batch, and limewater glassware can be priced on the same document.
