Question:

This problem incorporates ion-pair equilibria 12-12 and 12-13 into the acid-base chemistry of Section 12-1.
(a) From mass balance 12-15, derive Equation 12-16.
(b) Substitute equilibrium expressions into mass balance 12-17 to derive an expression for [T2-] in terms of [H+], [Na+], and various equilibrium constants.
(c) With the same approach used in part (b), derive expressions for [HT-] and [H2T].
