Sulphide ion in alkaline solution reacts with solid sulphur to form polysulphide ions having formulae `S_2^(2-),S_3^(2-),S_4^(2-)` and so on. The equilibrium constant for the formation of `S_3^(2-)` is 132 `(K_2)` , both from S and `S^(2-)` What is the equilibrium constant for the formation of `S_3^(2-)` from `S_2^(2-)` and S ?
