Question

The concentration of a certain ionic compound in aqueous solution is 0.186mol/L . It is only solute in the solution. The concentration of pottassium ions in the same solution ia 0.558mol/L. Explain why the concentrations of the ions in the solution are different. What might the ionic compound be?

Answer 1

0.558/0.186 = 3.00; therefore, if we call the anion A^-, the compound might b K3A. (K3PO4 would fit the bill.)
