The common-ion effect and solubility The solubility of aslightly soluble compound can be greatly affected by the additionof a soluble compound with a common ion, that is, with one of theions in the added soluble compound being identical to one of theions of the slightly soluble compound. The general result of theaddition of the common ion is to greatly reduce the solubility ofthe slightly soluble compound. In other words, the addition of thecommon ion results in a shift in the equilibrium of the slightlysoluble compound. Part B - Calculate the molar solubility in NaOHBased on the given value of the Ksp, what is the molar solubilityof Mg(OH)2 in 0.110 M NaOH?
