$B. Q \gt K_{sp}$

Work Step by Step

To predict the precipitation of a compound in a solution, we can calculate the $Q$ value for its concentration: $[AB] \lt -- \gt [A^+] + [B^-]$ $Q = [A^+] \times [B^-]$ If the calculated $Q$ is greater than the $K_{sp}$ for the compound $AB$, it will, most likely, precipitate.
