1. The concentration of Ag+ ion is a saturated aqueous solution of Ag2CrO4 was found potentiometrically equal to 1.56 x 10-4 M. Calculate the solubility in grams per liter and its solubility product. 2. The solubility product of a compound with a general formula M2X was found equal to 3.58 x 10-13 on the basis of solubility measurements and on the assumption that the ions formed are M7 and X-2. A more careful determination of the ionic species determined that...
