increases with a rise in temperature.

Answer 1

Question

1) The solubility of a crystalline solid increases with temperature. Does it

increase uniformly in all cases?

Answer:— Solubility often depends on temperature and this solubility increases with increasing temperature. Many salts show a large increase in solubility with temperature but it is not uniform.

Question

Name a substance, the solubility of which

answer:— KCl has large hydration energy than its lattice energy, so it evolves energy on dissolving in water. Consequently, with rise in temperature, its solubility increases.
