For this problem, we’re being asked to calculate the solubility of AgCl in 010 M MgCl2?
Since the compounds are ionic compounds, they form ions when dissociating in water. The dissociation of AgCl and MgCl2 in water are as follows:
The chloride ion, Cl–, has a charge of –1. Ag then has a charge of +1:
AgCl(s) ⇌ Ag+(aq) + Cl–(aq)
The chloride ion, Cl–, has a charge of –1. Mg then has a charge of +2:
MgCl2(s) ⇌ Mg2+(aq) + 2 Cl–(aq)
Calculate the Cl- concentration in 0.10 MgCl2.
= 0.2 M Cl-
The Ksp of AgCl is 1.6 x 10-10. What is the solubility of AgCl in 0.10 M MgCl2? Give your answer using scientific notation and to 2 significant figures (i.e., one decimal place).
