Question: How much calcium carbonate is there in limestone ?

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.

Answer: 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.
