Acetate is a chemical compound. It has the formula C2H3O2. It can also be called Acetate Ion. It is a salt that is formed by the mixture of acetic acid with some bases. The bases can be alkaline, metallic, earthy or nonmetallic. Conjugate base of acetic acid is Acetate. The abbreviation of acetate ion is AcO- or -OAc. Acetic acid is not a strong acid. It is a weak acid. It dissociates in water and releases a proton with an acetate ion. It happens at a pH of 5.5 or more. Chemical formula of Acetate is CH3COO-.

When vinegar that is also known as acetic acid and baking soda that is also known as sodium bicarbonate reacts with each other, they produce an acetate ester or sodium acetate. This reaction is well known and this mixture can be used for cleaning purposes.

If we talk about biology, acetate is considered as one of the most important building blocks for biosynthesis in the human body. It includes fatty acid synthesis. It is an anion and is found in Biology.

Properties Of Acetate ion

  • Molecular formula of Acetate ion is C2H3O2-.

  • Acetic acid is the conjugate acid of Acetate ion.

  • Molecular weight of Acetate ion is 59.04 g/mol.

  • 59.013 g/mol is the mass of acetate.

  • Complexity of Acetate ion is 25.5.

  • IUPAC name of Acetate ion is Ethanoate.

Structure Of Acetate

Acetate consists of one methyl group. This group is bonded with a carbonyl carbon. This carbonyl group is attached to another oxygen which is having a negative charge along with the methyl group. The hybridization of carbon of methyl is sp3 and it is having a tetrahedral geometry. The hybridisation of carbonyl carbon is sp2 .It is doubly bonded to oxygen and has a single bond with the oxygen that is negatively charged .Both the oxygen is equivalent . It is due to the electrons delocalization through resonance. The delocalization results in the equivalent distribution of the negative charge .

Chemical Properties Of Acetate

1. Acetate reacts with sodium hydroxide

When a reaction takes place between Sodium acetate and soda lime, methane and sodium carbonate are formed as a product. This type of reaction is called decarboxylation. It is one of the most common methods that is helpful in the preparation of alkanes.

2. Acetate reacts with Water

Water continuously ionises to form hydroxide anions and hydrogen cations. Sodium acetate gets dissociated in water to form sodium and acetate ions. Sodium ions do a small reaction with the hydroxide ions. And the acetate ions react with the hydrogen ions and produce acetic acid.
