In set I, Cu2+ has a higher charge density than Cu+, so CuS2- ions will be more strongly hydrated than CuS-. Therefore, Cu²⁺ will have a larger hydration energy than Cu⁺. In set II, Li+ is a smaller ion than NH4+, so it has a higher charge density and will be more strongly hydrated. Therefore, Li⁺ will have a larger hydration energy than NH₄⁺.
