Figure 2. Together potassium chloride (KCl) dissolves in water, the ions are hydrated. The polar water molecules are attracted by the fees on the K+ and Cl− ions. Water molecule in prior of and behind the ions are not shown.


In part cases, we find that solutions ready from covalent compounds command electricity due to the fact that the solute molecules react chemically with the solvent to create ions. Because that example, pure hydrogen chloride is a gas consists of covalent HCl molecules. This gas consists of no ions. However, once we dissolve hydrogen chloride in water, we uncover that the systems is a very good conductor.

The water molecule play an essential part in forming ions: remedies of hydrogen chloride in plenty of other solvents, such as benzene, carry out not conduct electricity and also do not contain ions.

Hydrogen chloride is one acid, and so its molecule react through water, transferring H+ ion to kind hydronium ions (H3O+) and also chloride ion (Cl–):
