A student followed the procedure of this experiment to determine the solubility product of zinc(II) iodate, Zn(IO3)2. Solutions of ZN(NO3)2 of known initial concentrations were titrated with 0.200 M KIO3 solutions to the first appearance of a white precipitate. The following data were collected.
Complete the table below and determine the solubility product constant.
[Zn(NO3)2]0, M Initial 0.226, 0.101 0.0452, 0.0118
[KIO3]0, M Titrant 0.200, 0.200, 0.200, 0.200
V0, mL of Zn(NO3)2 100.0, 100.0, 100.0, 100.0
V, mL of KIO3 titrant 12.9, 12.4, 13.0, 18.3
