Chromium salts are chemical compounds that contain the element chromium combined with other elements, typically forming ionic compounds. They are often used in various industrial applications, including dyeing, tanning leather, and as pigments in paints. Common types of chromium salts include chromium(III) chloride and chromium(VI) oxide. These salts can exhibit different colors and properties depending on their chemical structure. While some chromium salts are considered safe for use, others, particularly those containing chromium(VI), are toxic and can pose health risks. Proper handling and disposal are essential to minimize environmental and health impacts.
