The following compounds are only slightly soluble in water, but one of them is very soluble in a dilute aqueous solution of sodium hydroxide. The other is still only slightly soluble.

(a) Explain the difference in solubility of these compounds in dilute sodium hydroxide. (b) Show how this difference might be exploited to separate a mixture of these two compounds using a separatory funnel.
