Question

The dissociation of 0.15 M phosphoric acid is given by:

H3PO4(aq) + H2O(l) ⇄ H2PO4^-(aq) + H3O^+(aq)

Ka = 7.1 x 10-3 (at 25°C)

 

H2PO4^-(aq) + H2O(l) ⇄ HPO4^2-(aq) + H3O^+(aq)

Ka = 6.3 x 10-8 (at 25°C)

 

HPO4^2-(aq) + H2O(l) ⇄ PO4^3-(aq) + H3O^+(aq)

Ka = 4.5 x 10^-13

 

B. Applying the systematic method in solving acid-base equilibria problems, calculate the pH of the following

d. 0.050 M Na3PO4
