Indicate how the concentration of each aqueous species in the chemical equation changes to reestablish equilibrium after
changing the concentration of a reactant or product. Also indicate how the pH changes. An up arrow indicates an increase in
concentration, a down arrow indicates a decrease in concentration, and leaving it blank means there is no change in
the concentration.

A chemical system is set up by placing some solid ammonium chloride in an ammonia solution.
The equilibrium established can be represented as follows:
NH4*(aq) + H2O(e) 2 H30*(aq) + NH3(aq)
The pH of the solution is taken, then a small amount of NaOH(aq) is added and the pH is taken
again.
What can be said about the change in pH for the solution?
The pH significantly increases because a strong base has been added to the solution.
The pH significantly decreases because a strong base has been added to the solution.
There is very little change to the pH of the solution. If anything the pH of the solution
decreases slightly.
There is very little change to the pH of the solution. If anything the pH of the solution
increases slightly.
Calculate the pH of the resulting solution if 22.0 mL of 0.220 M HCl(aq) is added to 32.0 mL of 0.220 M NaOH(aq).
