Synonyms
From Wiktionary under the GNU Free Documentation License. Calcium carbonate is a chemical compound with the chemical formula Ca C O3. It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water. It is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous. From Wikipedia under the

From Google News Search: "calcium carbonate" How much calcium carbonate is there in limestone ? Q. I have to do an experiment for school (for chemistry more specifically) and have to do the research ourselves. I want to know how do you find out how much calcium carbonate is there in a limestone. What are the apparatus used and what is the procedure ? I need this info to write up the lab report. Any help will be appreciated. Asked by ashley21 - Tue Mar 25 07:04:19 2008 - - 3 Answers - 0 Comments A. While the first answer is essentially correct, limestone IS calcium carbonate, it is NOT pure calcium carbonate. most limestones contain other materials such as magnesium carbonate and silica. You can measure total carbonates by titration with an acid such as HCl. Alternatively, you can dissolve the limestone in a strong acid such as HCl or H2SO4 and then determine any residue left by weight.
