Problem 106P

A 75.0-L solution is 0.0251 M in Ca2+. If Na2SO4 is added to the solution in order to precipitate the calcium, what minimum mass of Na2SO4 is required to get a precipitate?

Step-by-Step Solution:

Solution 106P

Step 1:

Precipitation occurs when the ionic product exceeds the solubility product constant.

CaSO4  → Ca2+ + SO42-

Solubility product for CaSO4   = 7.10 x 10-5

Concentration of 75.0 L Ca2+ is 0.0251 M

We know,

Ksp = [Ca2+][SO42-]

[SO42-] = Ksp/ Ca2+]

           = 7.10 x 10-5/ 0.0251 = 2.83  x 10-3 M

Thus, minimum concentration of SO42-  2.83  x 10-3 M is required to get a precipitate of  CaSO4

Step 2:  

Moles of SO42-  = 2.83  x 10-3  mol/L x 75.0 L = 0.212  mol
