Question
Consider the equilibrium reaction: Ag2SO4 (s) = 2Ag+ SO4-2What would the effect of adding NH3 to form Ag(NH3)2+ in the reaction container?
No effects Equilibrium is reached faster Equilibrium reaction is shifted forward Equilibrium reaction is shifted in the reverse direction

Explanation / Answer
Ans: For this equilibrum reaction,
kc = [Ag+]2 [SO42-]
Now if we add NH3 to the solution Ag+ complexed as Ag(NH3)2+ ; concentration of Ag+ ions decreases in solution. To keep constancy of equil-m constant Kc concentration of sulfate ion to be increase ; equilibrium reaction shifted forward.
