What is the molarity of NaCl in which AgCl has a molar solubility of 2.38 x 10-9 mol /L? The Ksp for Silver Chloride is: 1.83 x 10-10.

The concentration of this NaCl solution is 0.0769M

Explanation:

Hello there!

In this case, since we are dealing with a solubility equilibrium in which it is desired to compute the concentration of a common-ion effect to chloride solution in the form of NaCl, we can set up the equilibrium reaction and expression:

It is possible to insert the concentration of starting chloride ions provided by the ionization of NaCl and in terms of the molar solubility, s, equal to 2.38x10^{-9}M:

Thus, solving for M, we obtain:

Thus, the concentration of this NaCl solution is 0.0769M.

Best regards!
