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 0.0700 M KH2PO4 + 0.5500 M K2HPO4.
What is the pH of this solution?
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=4.2x10-13)
What is [HPO4-2]?
What is [H2PO4-]?
