Dissolution of calcium chloride in water is exothermicprocess while that of ammonium nitrate is endothermic process, the observation is

Answer»

Solubility of CALCIUM chloridedecreases with increase in temperature and that of AMMONIUM nitrate increases with increase in temperature
Solubilities of both decreases with increase in temperature
Solubilities of both increases with increase in temperature
Solubilities of calcium CHLORIDE increases with increase in temperature and that of ammonium nitrate decrease with increase in temperature

Solution :For exothermic process increasing temperature , solubility decreases. For ENDOTHERMIC process increasing temperature, solubility increases.
