Calculate the concentration of potassium cations, [K' (aq); phosphate anions, [PO,3 (aq)); monohydro (aq)); and phosphoric acid, [H3PO4 (aq)] in a liter of 0.20 M potassium phosphate, K3PO4. Given the following information: (1) H3 PO4 (aq) + H20 (1) = H, PO4 (aq) + H30* (aq) Ka, = 6.9 x 10-3 (2) H2 PO4 (aq) + H20 (1) =HPO,2- (aq) + H3O* (aq) Kaz = 6.2 x 10-8 (3) HPO, (aq) + H20 (1) = PO,3- (aq) + H;0* (aq) Ka 2 - = 4.8 x 10-13 (4) Auto-ionization of water 2 H20 (1) = H30* (aq) + HO (aq) Kw = 1.0 x 10-14 Calculate the concentration of potassium cations, [K' (aq); phosphate anions, [PO,3 (aq)); monohydro (aq)); and phosphoric acid, [H3PO4 (aq)] in a liter of 0.20 M potassium phosphate, K3PO4. Given the following information: (1) H3 PO4 (aq) + H20 (1) = H, PO4 (aq) + H30* (aq) Ka, = 6.9 x 10-3 (2) H2 PO4 (aq) + H20 (1) =HPO,2- (aq) + H3O* (aq) Kaz = 6.2 x 10-8 (3) HPO, (aq) + H20 (1) = PO,3- (aq) + H;0* (aq) Ka 2 - = 4.8 x 10-13 (4) Auto-ionization of water 2 H20 (1) = H30* (aq) + HO (aq) Kw = 1.0 x 10-14
