Question
A solution of ammonia NH3(aq) is at equilibrium. How would the equilibrium change if NH4+ were added to the solution?A.The equilibrium would shift to produce more H+.B.The equilibrium would shift to produce more NH4+.C.The equilibrium would shift to produce more NH3.D.The equilibrium would shift to produce less NH4+.
Solution
The equilibrium of the solution would be affected by Le Chatelier's principle, which states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change.
In the case of ammonia in water, the equilibrium can be represented by the following equation:
NH3(aq) + H2O(l) ⇌ NH4+(aq) + OH-(aq)
If NH4+ is added to the solution, the equilibrium will shift to the left to reduce the increase in NH4+. This is because the system will try to counteract the change and restore equilibrium.
So, the equilibrium would shift to produce more NH3, which means the correct answer is C. The equilibrium would shift to produce more NH3.
