Calcium acetate is a chemical compound which is a calcium salt of acetic acid. It has the formula Ca(C 2 H 3 O 2) 2. Its standard name is calcium acetate, while calcium ethanoate is the systematic name. An older name is acetate of lime. The anhydrous form is very hygroscopic; therefore the monohydrate (Ca(CH 3 COO) 2 •H 2 O) is the common form.
When part of a salt, the formula of the acetate ion is written as CH 3 CO − 2, C 2 H 3 O − 2, or CH 3 COO −. Chemists often represent acetate as OAc − or, less commonly, AcO −. Thus, HOAc is the symbol for acetic acid, NaOAc for sodium acetate, and EtOAc for ethyl acetate [1] (as Ac is common symbol for acetyl group CH 3 CO [2] [3]).
Lead(II) acetate is a white crystalline chemical compound with a slightly sweet taste. Its chemical formula is usually expressed as Pb(CH 3 COO) 2 or Pb(OAc) 2, where Ac represents the acetyl group. Like many other lead compounds, it causes lead poisoning. Lead acetate is soluble in water and glycerin.
Silver acetate is a coordination compound with the empirical formula CH 3 CO 2 Ag (or AgC 2 H 3 O 2). A photosensitive, white, crystalline solid, it is a useful reagent in the laboratory as a source of silver ions lacking an oxidizing anion.
Barium acetate is generally produced by the reaction of acetic acid with barium carbonate: [2]. BaCO 3 + 2 CH 3 COOH → (CH 3 COO) 2 Ba + CO 2 + H 2 O. The reaction is performed in solution and the barium acetate crystalizes out at temperatures above 41 °C.
Anhydrous magnesium acetate has the chemical formula Mg(C 2 H 3 O 2) 2 and in its hydrated form, magnesium acetate tetrahydrate, it has the chemical formula Mg(CH 3 COO) 2 • 4H 2 O. In this compound magnesium has an oxidation state of 2 +. Magnesium acetate is the magnesium salt of acetic acid. [1]
Lead(IV) acetate or lead tetraacetate is an metalorganic compound with chemical formula Pb(C 2 H 3 O 2) 4. It is a colorless solid that is soluble in nonpolar, organic solvents, indicating that it is not a salt. It is degraded by moisture and is typically stored with additional acetic acid. The compound is used in organic synthesis. [2]
Manganese(II) acetate are chemical compounds with the formula Mn(CH 3 CO 2) 2 ·(H 2 O)n where n = 0, 2, 4. These materials are white or pale pink solids. Some of these compounds are used as a catalyst and as fertilizer. [3]
