###### Problem Details

Consider the reaction

YZ(s) ⇌ Y(aq) + Z(aq)

at equilibrium. If Ksp < [Y][Z], precipitation occurs.

The reaction quotient, Q, is also equal to [Y][Z]. Q is equal to Ksp only at equilibrium. When Q is less than Ksp, the solution is unsaturated; when Q is greater than Ksp the solution is supersaturated and precipitation could occur.

a. Enter the Ksp expression for A 2B3(s) in terms of [A] and [B].

b. Enter the Ksp expression for AC 4(s) in terms of [A] and [C].
