Question

2g of ammonium chloride is dissolved in 20cm3 of tap water whose initial temperature is 23°C, what's the final temperature of the solution?

Answer 1

Answer:

When ammonium chloride dissolves in water, heat is absorbed.

Thus, the dissolution of ammonium chloride is an endothermic reaction.

When the temperature of endothermic reaction is increased, the value of the equilibrium constant increases.

Hence, the solubility of ammonium chloride increases with increase in temperature.
