Using the data in your textbook calculate the concentrations of the molecular and ionic species and the pH in aqueous solution that has a formal composition of 0.2800 M KH2PO4 0.0600 M K2HPO4.What is the concentration of the molecular species H3PO4?What is the concentration of K in molarity?What is the concentration of OH-?What is the concentration of PO4-3 in molarity? (use Ka3=4.2×10-13)What is [HPO4-2]?What is [H2PO4-]?
