Why is the high energy required to transform Cu(s) to Cu2+(aq) not balanced by its hydration enthalpy?

Options

  1. ABecause Cu2+(aq) is unstable
  2. BBecause Cu2+(aq) has a high hydration enthalpy
  3. CBecause Cu2+(aq) is highly soluble
  4. DBecause Cu2+(aq) has a low hydration enthalpy

Correct answer

D. Because Cu2+(aq) has a low hydration enthalpy

Step-by-step solution

The high energy to transform Cu(s) to Cu2+(aq) is not balanced by its hydration enthalpy.
