A number of ionic compounds e.g.Agcl , caF2 BaSo4 are insoluble in water. This is because:
(1) Ionic compounds do not dissolve in water
(2) Water has a high dielectric constant
(3) Water is not a good ionizing solvent
(4) These molecules have exceptionally high alternative forces in the lattice
Ans; These molecules have exceptionally high alternative forces in the lattice
