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 *blank* the [a] when ac_4 begins to precipitate.
thus, when comparing a_2b_3 the one that will precipitate first is *blank*
