Normally, solubility of a crystalline solid increase with temperature. Does it increase uniformly in all cases ? Name a substance whose solubility :
(a) increase rapidly withe temperature.
(b) increase gradually with temperature.
(c) increase slightly with temperature.
(d) initially increases then decreases with rise in temperature.
Solubility of a solid in water always increases with increase in temperature.
Why does solubility increase with increase in temperature?
