An ionic formula, like (ce{NaCl}), is an empirical formula. This formula merely indicates that sodium chloride is made of an equal number of sodium and chloride ions. Sodium sulfide, another ionic compound, has the formula (ce{Na_2S}). This formula indicates that this compound is made up of twice as many sodium ions as sulfide ions.

Sodium chloride is an ionic compound. Many bonds can be covalent in one situation and ionic in another. For instance, hydrogen chloride, HCl, is a gas in which the hydrogen and chlorine are covalently bound, but if HCl is bubbled into water, it ionizes completely to give the H+ and Cl- of a hydrochloric acid solution.

However, these individual ions must be considered as possible reactants. Think of the solid ionic compound as a possible source of Mg 2 + and OH – ions. If a chemical reaction is possible, the ionic bonds between Mg 2 + and OH – will break. Step 2: Reaction of an acid (source of H +) and a base (source of OH-) will form water.

We can measure the partial charges on the atoms in a molecule such as HCl using Equation 3.4.2 If the bonding in HCl were purely ionic, an electron would be transferred from H to Cl, so there would be a full +1 charge on the H atom and a full −1 charge on the Cl atom. The dipole moment of HCl is 1.109 D, as determined by measuring the extent ...
