Solution
Carbon dioxide does not directly react with calcium carbonate instead it reacts with limewater() to form calcium carbonate (), which is then precipitated out of the solution. In addition to that, water is also produced. The balanced chemical equation for this reaction is given below;
Calcium carbonate precipitates out as solid particles of chalk. This makes the liquid turn ‘white milky’.
When an excess carbon dioxide is bubbled through the solution for an extended period of time, another acid-base reaction takes place and the solution turns out to be clear and colorless. It happens because of the formation of water-soluble calcium hydrogen carbonate().
The balanced chemical equation for this reaction is given as;
