What is acetate?
Acetate is a chemical compound with the formula C2H3O2−. It is also called acetate ion or monoacetate. It is a salt formed by combining acetic acid with alkali, metal, earth, nonmetal or other alkali.
The conversion of pyruvate to acetyl-CoA is carried out with the help of pyruvate dehydrogenase. Acetyl-CoA is further converted to acetate in Escherichia coli, while generating ATP through substrate-level phosphorylation. The whole process requires two enzymes, acetate kinase and phosphate acetyltransferase.
Acetate fermentation acetate charge
Acetic acid disproportionates to produce carbon dioxide and methane.

CH3COO− + H+ → CH4 + CO2 ΔG° = −36 kJ/mol

The reaction was carried out in the presence of catalyst methanogenic archaea. An electron is transferred from the carboxyl group of acetic acid to the methyl group, producing carbon dioxide and methane gas.
1. Reaction of acetic acid and sodium hydroxide

Sodium acetate and soda lime (NaOH + CaO) react to form methane and sodium carbonate. This reaction is called decarboxylation and is one of the common methods for preparing alkanes.

CH3COONa + NaOH → CH4 + Na2CO3

2. Acetate reacts with water

Water spontaneously dissociates into hydroxide anions and hydrogen cations. Sodium acetate dissociates into sodium ions and acetate ions in water. Sodium ions hardly react with hydroxide ions, while acetate ions combine with hydrogen ions to form acetic acid.

What elements are contained in acetate?

Both metal acetates are inorganic salts of metal cations and acetate anions, which are polyatomic ions (symbol: CH3COO) composed of two carbon atoms bonded to three hydrogen atoms and two oxygen atoms. The molecular formula is 59.05
What is the Difference Between Acetate and Acetic Acid?

The key difference between acetate and acetic acid is that acetic acid is a neutral compound whereas acetate is an anion with a net negative charge. Acetic acid is an organic compound that helps to produce vinegar, and the acetate ion is the conjugate base of acetic acid.
