Chloride vs. Chlorate: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 24, 2023

Chloride is an ion with the formula Cl⁻, while chlorate is an ion with the formula ClO₃⁻.

Key Differences

Chloride is an anion that consists of a single chlorine atom. It is the negatively charged counterpart to the element chlorine, which is found in its elemental state as a diatomic molecule, Cl₂. On the other hand, chlorate is a polyatomic ion consisting of one chlorine atom and three oxygen atoms. Chlorate is a member of the halate series, where halogens bond with oxygen in various ratios. While chloride ions are commonly found in nature as a result of the dissolution of salt in water, chlorate ions are typically synthesized in labs or produced through specific chemical reactions.

In terms of charge, the chloride ion carries a negative one (-1) charge, indicating it has gained an extra electron. Chlorate, in its common form, has a charge of negative one (-1) as well, but the distribution of its electrons among its four constituent atoms (one chlorine and three oxygens) is different. The presence of oxygen in chlorate gives it distinct chemical properties compared to the chloride ion.

Both chloride and chlorate ions are used in various industrial and chemical applications. Chloride is often associated with sodium to form table salt (sodium chloride) and is essential for life, playing a key role in the biology of all living organisms. Chlorate, however, is commonly used in herbicides, disinfectants, and as an oxidizing agent. It's worth noting that while both ions contain chlorine, their chemical behavior, due to the presence or absence of oxygen, can be quite distinct.

In terms of safety and environmental concerns, while chloride ions are generally safe and are an essential dietary element, chlorate can be harmful. Chlorate is a strong oxidizing agent and can pose risks if ingested or inhaled in large amounts. The two should not be confused, as their implications for health and the environment can vary widely based on their distinct chemical properties.
