1
Q
Why does the solubility of a saturated solution of NaCl increase when the solution is heated? enthalpy of solution of NaCl = +ve
A
The enthalpy of solution is endothermic
2
Q
State and explain what would happen if a saturated solution of calcium carbonate was heated.
A
enthalpy of solution is negative therefore when the solution is heated, the equilibrium shifts to the left to oppose the increase in temperature
