Look up the equilibrium constant for the ion-pairing reaction in Appendix J. (a) Use the systematic treatment

Question:

Look up the equilibrium constant for the ion-pairing reaction in Appendix J.

(a) Use the systematic treatment of equilibrium to find [Zn²⁺] in 0.010 F ZnSO4. Neglect activity coefficients and any other reactions.

(b) Use the answer from part (a) to compute the ionic strength and activity coefficients of Zn²⁺and SO²₄^-. Then repeat the calculation using activity coefficients. Repeat the procedure two more times to find a good estimate of [Zn²⁺]. What percentage is ion paired? What is the ionic strength of the solution?

(c) Two possibly important reactions that we did not consider are acid hydrolysis of Zn²⁺ and base hydrolysis of SO²₄^-. Write these two reactions and find their equilibrium constants in Appendixes I and G.
