Why Crystal Salt is dissolving faster than powder salt in water?
it must be your imagination unless the crystal salt and powder salt are different compounds. If both the salts are same the powder salt will dissolve much more readily. The solubility of a salt is a complex phenomenon and so only generalizations regarding salt solubility can be given. Generally the rate of dissolution increases with increasing surface area; thus, large crystals dissolve faster when ground into powder. Furthermore, the rate decreases with time since as the solid is dissolved the surface area becomes smaller as there is less and less crystallite. good luck with your chemistry.
