Calcium Hydroxide 200 gm
Calcium Hydroxide 200 gm (Product Code: SCI-531/230) is analytical reagent grade slaked lime used to prepare limewater for carbon dioxide tests and to demonstrate neutralisation in school and college laboratories. The 200 g pack is supplied with an MSDS, and because the solid is only sparingly soluble, a small amount makes a large volume of saturated limewater. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Calcium Hydroxide Used For?
The main classroom use is limewater. Shake a spoonful of calcium hydroxide with distilled water, let the excess settle and filter the clear saturated solution. Bubbling exhaled breath, or the gas from acid acting on marble chips, through it turns it milky as calcium carbonate forms, which is the standard test for carbon dioxide; prolonged bubbling clears it again as soluble calcium hydrogencarbonate forms.
Calcium hydroxide also shows how farmers neutralise acidic soil, how lime mortar hardens by absorbing carbon dioxide, and, when heated with ammonium chloride, how ammonia gas is prepared in the laboratory. Although only slightly soluble, it is a strong base that irritates skin and can seriously damage the eyes, so wear goggles, avoid raising dust and keep the container closed so the powder does not slowly turn to carbonate in air.

Related Laboratory Equipment
Limewater and gas-preparation practicals with Calcium Hydroxide 200 gm usually need:
- Calcium Carbonate (Granules) 200 g — reacts with dilute acid to produce the carbon dioxide tested with limewater.
- Filter Paper 120 mm — filters the saturated solution to give clear limewater.
- Calcium Oxide (Granules) 200 g — quicklime, which forms calcium hydroxide when water is added.
- Ammonium Chloride 200 g — heated with calcium hydroxide to prepare ammonia gas.
- Lime Water — a separately listed product for labs that prefer limewater ready-made.

Frequently Asked Questions
How is limewater made from Calcium Hydroxide 200 gm?
Stir a spoonful of Calcium Hydroxide 200 gm into distilled water, stopper and shake the flask, then leave the undissolved solid to settle. Filter or decant the clear liquid into a stoppered bottle; this saturated solution is limewater, ready for carbon dioxide tests.
Why does limewater made from calcium hydroxide turn milky?
Carbon dioxide reacts with dissolved Calcium Hydroxide to form insoluble calcium carbonate, which appears as a white milkiness. With excess carbon dioxide the milkiness clears again because soluble calcium hydrogencarbonate forms, a useful extension question for students.
Is Calcium Hydroxide 200 gm the same as quicklime?
No. Calcium Hydroxide 200 gm is slaked lime, Ca(OH)2, formed when quicklime (calcium oxide) reacts with water. Quicklime reacts vigorously and becomes hot when wetted, whereas calcium hydroxide is the stable product used to make limewater.
What is the shelf life of Calcium Hydroxide 200 gm?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Calcium Hydroxide 200 gm. Ask us for the expiry date of the batch you are quoted, and keep the lid tight because the powder slowly absorbs carbon dioxide from air.
Which vendor details are available for Calcium Hydroxide 200 gm orders?
Calcium Hydroxide 200 gm is supplied by Jain Scientific Equipments Private Limited, whose GSTIN and LEI are listed in the Supplier section for tender and vendor-registration forms. Send the number of 200 g packs and the delivery location through the contact page for a quotation.
