For the reaction Ag2S <====> 2Ag + S2 what happens to the equilibrium position if aqueous ammonium sulfide is added

Question

A. Shift left
B. Shifts right
C. Does nothing
D. Doubles
E. Halves

Answer 1

Ag2S(s) ==> 2Ag^+ + S^2-
(NH4)2S ==> 2NH4^2+ + S^2-

So adding the common ion, S^2-, will shift the equilibrium to the left.

Answer 2

;eft

Answer 3

I believe it would shift to the right, becasue the more reactant you have the more product you are able to make.

Answer 4

does nothing

Answer 5

shifts to the left
