. Ksp for Fe(IO3)3 is 10-14. Two solutions, one being iron(III) nitrate and the other being sodium iodate, were mixed. At the instant of mixing, [Fe3+] = 10-4M and [IO3-] = 10-5M. What happens?

Question

.  Ksp for Fe(IO3)3 is 10-14.  Two solutions, one being iron(III) nitrate and the other being sodium iodate, were mixed.  At the instant of mixing, [Fe3+] = 10-4M and [IO3-] = 10-5M.  What happens?

My answer is that a precipitate forms because Qsp > Ksp.

Would you agree?

No. Calculate Qsp again. And don't forget to cube IO3^- this time.
