Calculate the concentration of IO3 in a 7.56 mM Pb(NO3)2 solution saturated with Pb(IO3)2. The Ksp of Pb(IO3)2 is 2.5x10^-13. assume that Pb(IO3)2 is a negligible source of Pb compared to Pb(NO3)2.

A different solution contains dissolved Na(IO3). what is the concentration of NaIO3 if adding excess Pb(IO3)2(s) produces Pb=1.7x10^-6M
