Explain how the calcium carbonate helps to reduce the

Apr 14, 2013Best Answer Calcium carbonate chemically reacts with acids (the main acid in acid rain is sulphuric acid formed from sulphur dioxide emissions) to form a salt (e.g. calcium sulphate) water carbon dioxide gas. So what you see is 'fizzing' as the gas is evolved, and eventually the rock will disappear or dissolve.
