Dikromaattiioni

Dikromaattiioni is the chemical species with the formula Cr2O7^2-. It is an anion, meaning it carries a negative charge. The ion consists of two chromium atoms covalently bonded to seven oxygen atoms. Each chromium atom is in the +6 oxidation state, and the overall charge of the ion is -2. The dikromaattiioni is a strong oxidizing agent. It is commonly found in solutions containing chromic acid or alkali metal chromates and dichromates. The color of the dikromaattiioni is typically a vibrant orange. It exists in equilibrium with the chromattiioni (CrO4^2-) in aqueous solutions, with the equilibrium position depending on the pH. In acidic solutions, the dikromaattiioni is favored, while in basic solutions, the chromattiioni predominates. Dikromaattiioni is an important compound in various industrial processes, including metal plating, tanning of leather, and as an oxidizing agent in organic chemistry. However, due to its toxicity and carcinogenic properties, its use is increasingly restricted.
