Arsenate ions the formula AsO4^3. If 50.0 mL of 0.0010 M potassium arsenate is added to 200.0 mL of 1.0 x 10^-7 M cobalt (II) bromide, which of the following is true? The Ksp of the insoluble salt is 6.8 x 10^-29.

A. A precipitate will form Q< Ksp

B. A precipate will form because Q> Ksp

C. A precipitate will not form because Q<Ksp

D. A precipate will not form becsaue Q> Ksp

Answer is C please explain why and the process I keep getting Q greater than K
