Electrolytes are hydrated to different extent size of the ion is the deciding factor The radius of a water molecule assuming a spherical shape is approximately 1 40 Assume that water molecules cluster around each metal ion in a solution such that the water molecules essentiall touch both the metal ion and each other On this basis and assuming that 4 6 8 and 12 are the onl possible coordination numbers and size of cations as Mg2 radius 0 65 Rb radius 1 48 16 Al radius 0 50 Sr radius 1 13 Maximum number of water molecules that can hydrate Mg ion is A 4 C 12 B 6 D 8
