BRAINCAKELigand Substitution Reactions
If concentrated HCl is added to a solution of hexaaquacopper (II) ions the solution turns from blue to yellow. The tetrachlorocuprate (II) complex is more stable than hexaaquacopper (II) ions. There is little enthalpy change because bonds are of similar strength.
