Titrating 30.00 mL of a saturated calcium iodate solution requires 28.91 mL of a 0.092 M solution of Na2S2O3 according to the equation

IO3 – + 6S2O3 2– + 6H+ → I– + 2S3O6 2– + 3H2O

Calculate Ksp for Ca(IO3)2

a. 7.14 × 10–8

b. 6.97 × 10–4

c. 2.79 × 10–3

d. 1.61 × 10–6

e. none of these

I have the answer it is (D), But i would like a detailed solution on how to solve the question.
