The acid test on rocks. Marble is chemically calcium carbonate. Dolostone is a rock composed of almost entirely of dolomite. A student dropped a few pieces of marble in dilute hydrochloric acid contained in a test tube.

Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. The evolved gas was then passed through lime water. Marble is found in various places around the world including india greece spain turkey egypt italy and the united states of america. 2 hcl aq caco3 s cacl2 aq h2o l co2 g if you are talking about a marble counter top then i would advise against adding dilute hcl to that surface that because you will ruin it.

Marble chips are mostly made up of calcium carbonate which is a alkaline compound. Some rocks contain carbonate minerals and the acid test can be used to help identify them. What change would be observed in lime water. When you mix a strong acid like hcl with any carbonate you will have a chemical reaction in which co2 gas is released it will fizz.

What will happen if an excess of gas is passed through lime water. It will produce a very weak fizz when a drop of cold hydrochloric. A student dropped few pieces of marble in dilute hydrochloric acid contained in a test tube. The reaction takes place spontaneously.
