Chromium(III) acetate hydroxide [39430-51-8]

Chromium(III) acetate hydroxide, also known as basic chromium acetate, is an inorganic compound that features chromium (Cr), acetate (CH3COO-), and hydroxide (OH-) ions. The (III) in the name indicates that the chromium ion possesses a charge of +3, which is balanced by the negative charges from the acetate and hydroxide ions. In the molecule, three acetate ions and one hydroxide ion are typically coordinated to one chromium ion, forming a complex ion. The acetate ions are organic entities, each comprising a two-carbon chain with a methyl group (-CH3) and a carbonyl group (C=O). The hydroxide ion imparts basic properties to the compound. The presence of chromium, acetate, and hydroxide ions in Chromium(III) acetate hydroxide gives this compound distinctive chemical properties, including its reactivity, color, and solubility, which can be utilized in various areas of industrial and academic chemistry.
