A.

This is because BaSO₄ has the lowest solubility product out of all the substances.

If 0.2 M Ag+, 2 M Ba2+, and 2 M Ca2 + are added to a Na2SO4 solution, which will precipitate first? (Ksp of Ag2SO4 = 1.4 x 10-5, Ksp of BaSO4 = 1.1 x 10-10, and Ksp of CaSO4 = 9.1 x 10-6)A.) BaSO4B.) Ag2SO4C.) BaSO4 and CaSO4D.) Ag2SO4 and CaSO4
