In which of the following salts, the solubility increases appreciably with increase in temperature?
1 \(\mathrm{KBr}\)
2 \(\mathrm{NaBr}\)
3 \(\mathrm{NaCl}\)
4 \(\mathrm{KCl}\)
Explanation:
Solubilities of \(\mathrm{NaBr}, \mathrm{NaCl}\) and \(\mathrm{KCl}\) increases slightly with temperature, but for \(\mathrm{KBr}\), solubility increases appreciably.

Dissolution of a solute is an exothermic process if
1 hydration energy > lattice energy
2 hydration energy < lattice energy
3 hydration energy = lattice energy
4 none of the above
Explanation:
Heat of solution = Lattice energy (endothermic) + Hydration energy (exothermic) If Hydration energy > Lattice energy; heat of solution is exothermic.
