SALTS All solid salts consist of positive and negative ions, and some of them contain water molecules as well. The water in a lattice is called water of crystallisation. One mole of a hydrated salt always has a certain number of moles of water of crystallisation shown in the formula. For example, hydrated copper sulphate (CuSO4.5H2O) has five moles of water for each mole of the salt. GROUP 1 Group 1 elements are alkali metals. They are metals that are usually stored under oil or argon to stop t...
