SOLVED: Phosphoric acid (H3PO4) is a triprotic acid with pKa1=2.12, pKa2=7.21, and pKa3=12.32. NaH2PO4 is added to water to give a total concentration of 100 mg/L.(a) Write the mass balance for this solution.(b) Write the charge balance for this solution.(c) Write the proton condition for this solution.(d) Using the algebraic approximation method, calculate the equilibrium pH and the concentration of each chemical species in the solution.
