Question

With the rise in temperature the solubility of sodium chloride in water:
A. Decreases
B. Increases and then decreases
C. Increases sharply
D. increases only a little​

Answer 1

With the rise in temperature the solubility of sodium chloride in water increases sharply.

Explanation:

• Solubility of solid in a liquid depends on the nature of the solid.

• It depends on whether the dissolution process is exothermic or endothermic. Using Le Chatelier's principle, if the temperature is increased for an exothermic process then dissolution decreases and if the temperature is increased for an endothermic process then dissolution increases.

• The heat of solution of NaCl is very small as the heat of ionization is nearly equal to the heat of hydration.

• Therefore, temperature doesn't affect the dissolution of NaCl as the heat of hydration almost equalizes heat of dissolution.
