WebWhen some substances crystallise from solution, water becomes chemically bound up with the salt. This is called water of crystallisation and the salt is said to be hydrated. For example, hydrated copper sulfate has the formula CuSO 4 .5H 2 O which formula indicates that for every CuSO 4 in a crystal there are five water (H 2 O) molecules.

As ice occupies 9% more volume than water, it exerts pressure within the joints. 2. When water freezes within the rock it attracts small particles of water, creating increasingly large ice crystals. In either case the process slowly widens the joints and, in time, causes process of rock to shatter (or disintegrate) from the main rock.
