Water is polarised with a slightly negative ‘end’ and a slightly positive ‘end’, oxygen being far more electronegative than hydrogen. These negative ‘ends’ are attracted to the positive ions in the lattice and attempt to surrond them as the substance is crystallising from aqueous solution. The same happens between the positive ends of the water dipoles and the negative ions in the lattice. The final structure adopted depends on the size of the ions and the forces between them as well as the organisation (body cell structure) of the lattice.
