Carbon dioxide reacts with water to form carbonic acid (Equation 1). Carbonic acid then dissociates to give the hydrogen ion (H +) and the hydrogen carbonate ion (HCO 3-) (Equation 2).The ability of H 2 CO 3 to deliver H + is what classifies this molecule as an acid, thus lowering the pH of a solution.

Calcium - Simple English Wikipedia, the free encyclopedia
It reacts with water to produce hydrogen and calcium hydroxide.It reacts with water very fast when it is powdered. When it is in a chunk, it starts reacting slowly because calcium hydroxide makes a coating that does not dissolve on the calcium. If a little acid is added to calcium hydroxide, it dissolves it, making the calcium react very fast.
