Using the correct formula for the green crystals write a balanced chemical equation for their synthesis. The reactants were iron (III) chloride, potassium oxalate and water. A second product of the synthesis is potassium chloride. Note: the waters of hydration in the iron(III) chloride, and potassium oxalate should not be shown. Include phase labels. Using the masses of iron (III) chloride hexahydrate and potassium oxalate monohydrate from Data Table A, calculate the theoretical yield of green crystals. This is a...
