If A is slowly added to a solution containing 0.0500 M of B and 0.0500 M of C, which solid will precipitate first? The solubility product constant for A2B3 is 2.30×10−8. The solubility product constant for AC4 is 4.10×10−8. Fill in the blanks below.

The [A] when A_2B_3 begins to precipitate is about the [A] when AC_4 begins to precipitate.

Thus, when comparing A_2B_3 the one that will precipitate first is
