II. Solutions in which the Solute Ionizes and Dissociates
Many ionic compounds are highly soluble in water because of the strong attraction between ions and the highly polar water molecules. This also applies to organic compounds that can exist as ions. For example, sodium acetate consists of Na+ and CH3COO- ions, which are highly soluble in water. Although there are some exceptions, you may assume in this experiment that all organic compounds that are in the ionic form will be water-soluble.
The most common way by which organic compounds become ions is in acid-base reactions. For example, carboxylic acids can be converted to water-soluble salts when they react with dilute aqueous NaOH:
