This solution of AgCl is used to dissolve several salts. Which salt will be most soluble in this solution given that all conditions are held at the same temperature and pressure?
A) silver nitrate
B) sodium chloride
C) potassium bromide
D) potassium chloride
Since the other three salts have a common ion to the solution (either Ag or Cl), potassium bromide will dissolve more readily. This is due to the common ion effect affecting solubility.
