A student performing the lab for the solubility of calcium iodate, titrated a 10.00ml sample of saturated calcium iodate solution with a 0.011 M sodium thiosulfate solution. The titration required 21.62 ml to turn he solution clear. What was the concentration of the iodate in the solution? What was the Ksp that the student determined for the titration?
