Question

Why is cu2+ more stable than cu+ in aqueous solution in basic medium?

Answer 1

comparing to Cu+, Cu2+ has a high density of positive charge. and the heat of hydration is increased as its charge density increases.So Cu2+ releases more heat as it dissolves.Then it achieves more stronger bonds with water molecules than Cu+.so although Cu+ appears to be more stable with electron configuration,actually Cu2+ has more stability in solutions .

Answer 2

cu2+ has more ion density then cu+ and thus forms morr stable bonds with water.So cu2+ releases more heat while bonding with water than cu+.Stability depends on density of hydration energy of ions....

hope this helps you..
