For this problem, we’re being asked to calculate the solubility (in g/L) of AgCl(s) in 0.0010 M FeCl3(aq). Since the compounds are ionic compounds, they form ions when dissociating in water. The dissociation of AgCl and FeCl3 in water are as follows:

The chloride ion, Cl, has a charge of –1. Ag has a charge is +1:

AgCl(s)  Ag+(aq) + Cl(aq)

The chloride ion, Cl, has a charge of –1. Fe has a charge is +3:

FeCl3(s)  Fe3+(aq) + 3 Cl(aq)

Calculate the molarity of Cl-:

= 0.0030 M Cl-

Notice that there is a common ion present, Cl. The common ion effect states that the solubility of a salt is lower in the presence of a common ion.
