the value for the Ksp of silver chromate is reported to be 1.1 x 10^-12. in a saturated solution of silver chromate, the silver ion concentration is found to be 2.5 x 10^-4M. what must the chromate ion concentration be?

• chemistry -

Ag2CrO4 ==> 2Ag^+ + CrO4^-2

Ksp = (Ag^+)^2(CrO4^-2)
Plug in Ag^+ from the problem, square it, divide by Ksp in the problem and Voila, the (CrO4^-2) = ??

• chemistry -

1.1 x 10^-12
