Alum usually the sulphate salt of two metals 1:1 together, potassium and aluminium. Potassium ion is 1+, aluminium ion is 3+, and sulfate ion is 2-. So, the correct formula should be KAl(SO4)2, but usually it is found as dodecahydrate form, that is there are 12 molecules of water in each unit cell. Hence, it is KAl(SO4)2.12H2O, but sometimes it can be written as K2SO4.Al2(SO4)3.24H2O with sulphate of potassium and aluminium being written separately.
So both are correct but technically speaking first one is correct.
