Question 1106018: The solubility equilibrium constant for the dissolution of copper (I) chloride into copper ions and chlorine ion is Ksp = [Cu+][Cl-].
If the solubility constant is Ksp = 1.7 × 10-7, and the concentration of chlorine (Cl-) is 0.2 mol/L greater that the concentration of copper (Cu+), what is the concentration of copper ions in solution?

You can put this solution on YOUR website!
Chloride, NOT Chlorine.
Your solution contains chloride ANIONS.

x, molarity of cuprous ion
x+0.2, molarity of chloride ion

x%28x%2B0.2%29=1.7%2A10%5E%28-7%29

Solve this quadratic equation for x.
(Only a positive value will make sense).
