| ion exchange |
Most common ion exchange systems use a zeolite resin bed and simply replace unwanted ions (Ca 2+ and Mg 2+ ) with benign (soap friendly) sodium or potassium ions. This is the common water softener. A more rigorous type of ion exchange swaps hydrogen (H + ) ions for unwanted cations and hydroxide (OH - ) ions for unwanted anions. The result is H + + OH - --> H 2 O. This system is recharged with hydrochloric acid and sodium hydroxide. The result is essentially deionized water.

| ionizing radiation |
Radiation that knocks an electron from a molecule, thereby making it positively charged. The free electrons can form charged ions in living tissue that react with and damage cells. It can be used to destroy microorganisms and germs in food products.

| ion |
An atom or molecule that carries a net charge (either positive or negative) because of an imbalance between the number of protons and the number of electrons present. If the ion has more electrons than protons, it has a negative charge. If the converse is true, the ion has a positive charge. Ions with a positive charge are called cations; ions with a negative charge are called anions.
