Question

degree of hydration of li+ is greater than the k
+

Answer 1

Your question is"Why degree of hydration of Li+ is greater than K+"?The answer is that:*The smaller the size of the ion, the greater is its degree of hydration--> Because the smaller the size-> more will be its charge density-> more will be its attraction for the polar solvent molecules.* Thus, Li+ ion(smaller)-> gets more hydrated than the K+ ion(larger).
