If the reaction of phosphate ion with water is ignored,what is the total concentration of ions in a solution prepared by dissolving 7.00 g of K₃PO₄ in enough water to make 350.mL of solution?

Question

Quizplus · Accepted Answer

The molar mass of K3PO4 is approximately 212.27 g/mol. Dissolving 7.00 g in 350 mL (0.350 L) gives a concentration of 0.0943 M for K3PO4. Since K3PO4 dissociates into 4 ions (3 K+ and 1 PO4^3-), the total ion concentration is 4 times 0.0943 M, which equals 0.377 M.
