the right hand panel of Figure 1. Benzanilide, a neutral compound, shows almost no change in retention while benzoic acid has a very noticeable change in retention as the pH is shifted from 3 to 7. At pH 7, well above the pKa of benzoic acid, it exists as the ionized benzoate anion. This form is more ionic, prefers the aqueous mobile

Acid

An acid-base extraction operates on the same principle, but can provide a further level of fine-tuning. If one or more of the compounds in the mixture to be separated is acidic or basic, the solubilities of these acidic and basic components can be manipulated to our advantage by applying simple acid-base

many cases, qualitative analysis will also involve the separation of ions or compounds in a mixture. Examples of qualitative tests would include ion precipitation reactions (solubility tests) or chemical reactivity tests. The separation of ions is easily achieved by taking advantage of their solubility properties (Flow-Chart 1). Flow-Chart 1.
