The video tutorial explains how some ionic compounds, like copper sulfate, can trap water molecules within their crystal structure, forming hydrated compounds. It covers the classical and IUPAC methods for naming these compounds, using prefixes to indicate the number of water molecules. The tutorial also discusses the solubility of ionic compounds in water, differentiating between those that dissolve to form aqueous solutions and those that remain solid. Examples like sodium chloride and calcium carbonate are used to illustrate these concepts.
