Problem: 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).

FREE Expert Solution

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.

0.10 mol MgCl21 L ×2 mol Cl-1 mol MgCl2

= 0.2 M Cl-
