Question

A solid whose solubility increases slightly with rise in temperature
1.NaCl
2.CaSO₄
3.CuSO₄
4.NH₄Cl​

Answer 1

Explanation:

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 and NaCl solubility slightly increases with temperature.
