Explain the solubilities of ammonium nitrate, 'calcium chloride, ceric sulphate and sodium chloride in water at different temperature with a graph.

Explanation

(i) The solubility of sodium chloride does not very appreciably as the maximum slubility is achieved at normal temperature. In fact, there is only `105` increase in solubility between `0^(@)C` to `100^(@)C.`
(ii) The dissolution process of ammonium nitrate is endothermic, the solubility increases with increase in temperature.
(iiii) In the case of ceric sulphate, the dissolution is exothermic and the solubility decreases with increase in temperature.
(iv) Even though the dissolution of calcium chloride is exothermic, the solubility increases role in deciding the position of equilibrium.
