Solution
FeCl3 with oxalic acid in aqueous KOH solution to form complex, K3[Fe(C2O4)3].
The reaction is, FeCl3+3H2C2O46KOH−−−−→K3[Fe(C2O4)3]+3KCl+6H2O
The secondary valencies are non-ionisable. These are satisfied by neutral molecules or negative ions. A secondary valency is equal to the coordination number.
