Question

A solution of ammonia NH3(aq) is at equilibrium. How would the

equilibrium change if OH were added to the solution?
A. [NH4+] and [OH-] would increase.
B. [NH4+] would increase and [OH] would decrease.
C. [NH4+] and [OH-] would decrease.
D. [NH4+] and [H+] would decrease.

Answer 1

Answer:The addition of OH- to the solution would shift the equilibrium to the left, resulting in a decrease in [NH4+] and [OH-]. Therefore, option B is correct.
