###### Problem Details

For BaCrO4 (Ksp = 1.17 × 10–10), will a precipitate of BaCrO4 form when 0.10 L of  6.0 × 10–2 M Ba(NO3)2 is added to 400 mL of 5.0 × 10–8 M Na2CrO4?

A)      Yes, because Q > Ksp.              D)        No, because Q = Ksp.

B)      No, because Q < Ksp.                E)        Yes, because Q < Ksp.

C)      Yes, because Q = Ksp
