Answer:
Yes, the solubility of a substance changes with
temperature,
The maximum amount of a solute which can be dissolved in
100 g of a solvent at a specified temperature is called its solubility,
Effect of temperature on solubility
(i) The solubility of solids in liquids usually increases
on increasing the temperature and decreases on decreasing the temperature.
(ii) The solubility of gases in liquids usually decreases
on increasing the temperature and increases on decreasing the temperature.
Let us take an example of copper sulphate.
The solubilities of copper sulphate in water at various
temperatures are given below
From the above data, it is clear that, when the temperature is increased
from 0°C to 70'C, the solubility of copper sulphate in water increases from 14
g to 47g. The above data shows that the solubility of a salt increases on
increasing the temperature.
