Hydration of ions in solution is associated with
absorption of heat
reduction of heat
conduction of heat
liberation of heat
Explication
The hydration of ions in solution is associated with the liberation of heat because it's an exothermic process, meaning it releases energy. This is due to the lowering of the potential energy of the ions and water molecules when they form new forces of attraction.
