You are provided with a 0.0588 M of sodium citrate (the dibasic salt), NaH2C6H5O7. In the aqueous solution, the sodium salt dissociates completely to provide a solution containing the amphiprotic species, H2C6H5O7─.

As a base: H2C6H5O7− (aq) + H2O(l) ⇌ H3C6H5O7 (aq) + OH1-(aq) Kb= 1.35 x 10-11
As an acid H2C6H5O7− (aq) + H2O(l) ⇌ H3C6H5O7 (aq) + H3O+ (aq) Ka =1.7 x 10 -5

H2C6H5O7─ behaves as an acid or a base?
Justify your choice in a sentence.

Use the appropriate equilibrium equation from question 9 (appropriate for the behavior of H2C6H5O7─ , Kb if it behaves as a base, or Ka if it behaves as an acid)

Calculate the pH, pOH and the [H+] of an aqueous solution that is 0.0588 M in H2C6H5O7─ and 0.10 M in the appropriate conjugate of this anion.
