Nitric acid and calcium hydroxide react to form calcium nitrate and water.
The molecular equation is as follows:
2HNO3 (aq) + Ca(OH)2 (aq) = Ca(NO3)2 (aq) + 2H2O (l)
So the formula of calcium nitrate, the salt formed in this reaction is Ca(NO3)2 .
Water here seem to be the only real product. It is formed from the OH+ of the hydroxide and the H+ of the acid which combine to form two water molecules.
Calcium and Nitrate ions remain unchanged before and after the reaction and are thus known as spectator ions.
