Explain molecular and ionic species in an aqueous solution

Reference no: EM13259440

The next 6 questions involve the calculation of concentrations of the molecular and ionic species in an aqueous solution that has an analytical composition of 0.060 M KH2PO4 + 0.460 M K2HPO4.

NOTE: The Ka's for the three acidic protons of phosphoric acid H3PO4 are: 7.11 x 10-3, 6.32 x 10-8, and 4.5 x 10-13. It may be helpful to write out the three dissociation reactions along with their Ka's and pKa's before starting these problems.

1) What is the concentration of K+ in molarity?

2) What is the concentration of OH-?
