Calcium Carbonate
Calcium Carbonate (Product Code: JSS-799/144) is an analytical reagent carbonate salt used to prepare carbon dioxide and to study acid-carbonate reactions, rates of reaction and thermal decomposition in school and college chemistry laboratories. The same compound that makes up limestone, chalk and marble, it is a basic stock item on school chemistry lab equipment lists in India and comes in a 500 gm pack with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Calcium Carbonate Used For?
To prepare carbon dioxide, calcium carbonate is placed in a flask fitted with a thistle funnel and delivery tube, and dilute hydrochloric acid is poured in a little at a time. The gas is collected in gas jars by upward displacement of air and identified by turning lime water milky and putting out a burning splint. The same reaction illustrates the general rule that an acid and a metal carbonate give a salt, water and carbon dioxide.
For a rate-of-reaction investigation, a flask of acid and carbonate stands on a digital weighing balance and the loss in mass is recorded as carbon dioxide escapes, repeated at different acid concentrations or temperatures. Heating a small sample strongly in a hard-glass tube shows thermal decomposition to calcium oxide. The reaction with acid froths, so use a flask with room to spare and add acid slowly. The salt itself is low-hazard, but keep the dust out of eyes and store the pack dry.
Supplier
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana. The company supplies reagents, including common salts like this one, to schools, colleges and distributors in India and international markets, and can quote them in the same enquiry as the gas-preparation glassware.

Related Chemistry Lab Products
The carbon dioxide and decomposition experiments use these items alongside it:
- Hydrochloric Acid Dilute — reacts with the carbonate to give carbon dioxide.
- Delivery Tube — leads the gas from the flask to the collecting jar.
- Gas Jar — collects the carbon dioxide for testing.
- Lime Water — turns milky to confirm carbon dioxide.
- Calcium Oxide (Powder) Purified — the quicklime formed by strong heating, for comparison.

Frequently Asked Questions
Who supplies Calcium Carbonate JSS-799/144?
Calcium Carbonate (JSS-799/144) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources this analytical reagent salt for school and college practicals and supplies it with an MSDS to institutions and dealers in India and international markets.
How much does one pack of Calcium Carbonate contain?
One pack of Calcium Carbonate contains 500 gm of the salt, listed as analytical reagent grade and supplied with an MSDS. Schools running carbon dioxide preparation with several practical groups can request more than one pack in a single enquiry.
Is the calcium carbonate powder or chips?
The listing for Calcium Carbonate does not state the physical form. Chips give a steadier gas flow for carbon dioxide preparation, while powder reacts faster, so confirm which you need through our contact page before ordering.
Why does the flask froth over with calcium carbonate and acid?
Calcium Carbonate releases carbon dioxide quickly when it meets acid, especially if the material is fine or the acid is strong. Add the acid in small portions and use a larger flask so that the froth stays inside the apparatus.
Can calcium carbonate be used to show how antacids work?
Yes. Calcium Carbonate works well as a laboratory demonstration of an acid being neutralised by a carbonate, as happens with antacid tablets. It is a laboratory reagent, not a medicine, so it must not be tasted or swallowed during the lesson.
What is the shelf life of Calcium Carbonate?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Store Calcium Carbonate in a closed container in a dry cupboard, with its MSDS kept alongside your chemical records.
