In this problem, we are asked to find the highest concentration of the potassium ions among the solutions with a molar of 0.20 M KCl, 0.15 M K2CrO4, or 0.080 M K3PO4.


MOLARITY (M) represents the moles of solute dissolved per liters of solution.

M=moles of soluteLiters of solution


In answering this problem, we must:

Step 1. Know the individual ions in each compound.

Step 2. Find the concentration of potassium ions in each compound.

Step 3. Compare the concentrations of potassium ions in each compound.
