Anhydrous magnesium acetate has the chemical formula Mg(C₂H₃O₂)₂ and in its hydrated form, magnesium acetate tetrahydrate, it has the chemical formula Mg(CH₃COO)₂ • 4H₂O. In this compound magnesium has an oxidation state of +2. Magnesium acetate is the magnesium salt of acetic acid. It is deliquescent and upon heating, it decomposes to form magnesium oxide. Magnesium acetate is commonly used as a source of magnesium in biological reactions.
