Question
Sulfide ion in alkaline solution reacts with solid sulfur to form polysulfide ions having formulae S22-, S32-, S42- and so on. The equilibrium constant for the formation of S22- is 12 (K1) & for the formation of S32- is 132 (K2), both from S and S2-. What is the equilibrium constant for the formation of S32- from S22- and S ?
Options
A.11
B.12
C.132
D.None of these
Solution
S (s) + S2- (aq) ⇋ S22- (aq) K1 = 12
2S (s) + S2- (aq) ⇋ S32- (aq) K2 = 132
Now , S22- (aq) + S (s) S32- (aq) Keq =
= 11
2S (s) + S2- (aq) ⇋ S32- (aq) K2 = 132
Now , S22- (aq) + S (s) S32- (aq) Keq =
= 11Create a free account to view solution
