The dissolution of ammonium chloride in ...

The dissolution of ammonium chloride in water is an endothermic process but still it dissolves in water readily. Why ?

Text Solution

Verified by Experts

It takes heat frojm surroundings so as to overcome lattice enegry therefore, it dissolves and yet the process is endothermic but `DeltaS is +ve`
