Hexavalent refers to a chemical state in which an element has a valence of six, meaning it can form six bonds with other atoms. This term is often associated with certain elements, such as chromium, which can exist in multiple oxidation states. Hexavalent compounds can be found in various industrial applications, including pigments and corrosion inhibitors. One of the most notable hexavalent compounds is chromium(VI), which is known for its toxicity and potential health risks. Exposure to hexavalent chromium can lead to serious health issues, including respiratory problems and cancer. Due to these dangers, regulations have been established to limit its use and protect public health.
