Question

When ammonium chloride dissolves in water, the temperature of the solution reduces.

• A. True
• B. False

Answer 1

The correct option is A True

• When ammonium chloride(NH₄Cl) is dissolved in water (H₂O), the temperature of the solution reduces.
• This is because ammonium chloride absorbs heat from the water and due to this the temperature of the solution reduces.
• This energy change is called endothermic.
• The reaction in which absorption of heat takes place is called an endothermic reaction.

Therefore, the statement When ammonium chloride dissolves in water, the temperature of the solution reduces is true.
