Consider the equilibrium: AgCl(s) + 2NH3(aq) ⇌ [Ag(NH3)2]+(aq) + Cl-(aq), which changes will decrease the equilibrium concentration of [Ag(NH3)2]+(aq)?
Options:(select one or more)
Answer:
A, D
Solution:
NaCl(s) raises [Cl-], so the equilibrium shifts backward and [Ag(NH3)2]+ falls, so (a) decreases it Adding solid AgCl changes no concentration, so (b) has no effect
Extra concentrated NH3 shifts the equilibrium forward and raises [Ag(NH3)2]+, so (c) increases it
Adding water dilutes every dissolved species, so [Ag(NH3)2]+ falls, and (d) decreases it
The answer is (a) and (d).
