Phosphoric acid is triprotic with the step-wise dissociation shown below. A 1.75 M phosphoric acid solution is prepared. Calculate the equilibrium concentrations of the species indicated. Report all answers in scientific notation using 2 sig figs. Rather than use the quadratic equation, you can make assumptions like we do in class (ie if K<<1, then 0.1-x ~ 0.1). Please fill in blanks below all species. Please answer each equilibrium concentration of each species in scientific notation. H3PO4H3PO4 + H2OH2O ↔↔...

Phosphoric acid is a triprotic acid To find the pH of a buffer composed of H2PO4^-(aq) and HPO42^-(aq), which pKa value would you use in the Henderson-Hasselbalch equation? Calculate the pH of a buffer solution obtained by dissolving 27.0 g of KH2PO4(s) and 38.0 g of Na2HPO4(s) in water and then diluting to 1.00 L.
