Question:
Look up the equilibrium constant for the ion pairing reaction Zn2+ + SO42- ↔ ZnSO4(aq) in Appendix J. (Found to be 2.34)
a) Using the systematic treatment of equilibrium, and neglecting the activity coefficients and any other reactions, the molar concentration of Zn2+ was found to be______ in 0.019 F ZnSO4.
b) Use the answer in part (a) to compute the ionic strength and activity coefficients of Zn2+ and SO42-. Then repeat the calculation using activity coefficients. Repeat the procedure two more times to find a good estimate of the molar concentration of Zn2+to be_____. Report the answers to two significant figures.
