MgCl2 ==> Mg^2+ + 2Cl^-
.........0.23....0.46
Substitute those number into the Ksp expression and solve for Ksp.
part 2.
Then Ksp = (Mg^2)(Cl^-)^2
Plug in 0.00537 for Mg^2+ and solve for Cl^-.
The molar solubility of magnesium chloride in water is 0.23 M.
What is the numerical value for Ksp for MgCl2?
Suppose you wanted to reduce the concentration of dissolved Mg2+ to 0.00537 M by adding NaCl. What concentration of NaCl would you need?
