Solubility Settlement (Posted on 2013-03-15) Difficulty: 3 of 5
The solubility product of MCO3 in water is 25 times as great as the solubility product of MC2O4 in water at the same temperature. A mixture of K2CO3 and K2C2O4 totalling 2.042 x 10-3 mole was dissolved in water. To this solution was added 2.80 x 10-3 mole of MCl2.

Water was then added to give a total volume of one liter. When precipitation was complete a mixture of MCO3 and MC2O4 totalling 2.000 x 10-3 mole had precipitated.

Calculate the solubility product for MC2O4.

*** M is the chemical symbol of an unknown metal.
