A 45.00 mL saturated solution of Cd(IO3)2 (Ksp=2.3x10^-8) was added to 15.00 mL of 0.0500 M KIO3. Calculate the equilibrium concentrations of IO3- and Cd2+. Assume volumes are additive, and the temperature remains constant. Show your calculations. IF you make any assumptions, make sure to test its validity.
