Question

Whether the solubility of ammonium chloride in water increases on increasing temperature. Why?

Answer 1

Step 1 Understanding the concept:

• Ammonium chloride is an inorganic compound that is soluble in water.
• The maximum amount of solute that can dissolve in a solvent at equilibrium is known as solubility.
• The solubility of a solution is determined by its temperature, pressure, and other substances.

Step 2 Explanation:

• Ammonium chloride is an inorganic compound and a neutral salt that does not completely dissociate when added to water.
• As the temperature rises, the dissociation of ammonium chloride rises, increasing its solubility.
• When dissolution occurs, heat is absorbed, indicating that the reaction is endothermic.
• As the temperature rises, the value of the equilibrium constant rises as well.
• As a result, as the temperature rises, so does the solubility of ammonium chloride increase.
