Chloride
Chloride is an ion of chlorine. It occurs when chlorine gets reduced, gaining an electrons and becoming an ion. Chloride is necessary for life. It is normally found in the salt (sodium chloride), which is very common in diets.
"Chloride" is also used as a general name for chemical compounds containing chlorine in the -1 oxidation state, whether or not they contain a chloride ion. Most compounds containing chlorine are chlorides in this sense. The main exception is if chlorine is bonded to oxygen or fluorine.

The structure of sodium chloride, revealing the tendency of chloride ions (green spheres) to link to several cations.
Basic membrane cell used in the electrolysis of brine. At the anode (A), chloride (Cl−) is oxidized to chlorine. The ion-selective membrane (B) allows the counterion Na+ to freely flow across, but prevents anions such as hydroxide (OH−) and chloride from diffusing across. At the cathode (C), water is reduced to hydroxide and hydrogen gas.
