High hydratio...

Question

High hydration enthalpy of lithium makes it less reactive with water.High hydration enthalpy means more soluble/less soluble?

Open in App

Solution

Hydration enthalpy of an ion is the amount of energy released when a mole of the ion dissolves in a large amount of water forming an infinite dilute solution in the process,.
Lithium is highly hydrated due to its smaller size and positive charge. High hydration enthalpy means more soluble in water.
