Problem- A mixture contains both potassium phosphate and potassium chloride. What is the percentage of potassium phosphate in this mixture if reaction of 0.401 g of this mixture with excess copper ii chloride yields 0.213 g of copper ii phosphate? Assume that the potassium phosphate is not hydrated.
