Consider three hypothetical ionic solids: AX, AX2, and AX3 (each X forms X). Each of these solids has the same Ksp value, 5.5 ×10–7. You place 0.25 mol of each compound in a separate container and add enough water to bring the volume to 1.0 L in each case.
a. Write the chemical equation for each of the solids dissolving in water.
