Determine the molar solubility of CuCl in a solution containing 0.050 KCl. Ksp of CuCl is 1.0 x 10-6

Explanation:

Hello!

In this case, since the dissolution of copper (I) chloride is:

And its equilibrium expression is:

We can represent the molar solubility via the reaction extent as , however, since there is 0.050 M KCl we immediately add such amount to the chloride ion concentration since KCl is readily ionized; therefore we write:

Thus, solving for , we obtain:

By using the quadratic equation, we obtain:

Clearly, the solution is because no negative results are

allowed. Therefore, the molar solubility is:

Best regards!

the answer is 303.15 or 303
