|Section2= |Section3= }} Sodium diacetate is a compound with formula . It is a salt of acetic acid. It is a colorless solid that is used in seasonings and as an antimicrobial agent. ==Preparation and structure== The salt forms upon half-neutralization of acetic acid followed by evaporation of the solution. It can be viewed as the result of homoassociation, an effect that enhances the acidity of acetic acid in concentrated solution: : 2 CH3CO2H + NaOH → Na+()− + H2O Also described as the sodium acid salt of acetic acid, is best described as the sodium salt of the hydrogen-bonded anion (CH3CO2)2H−. The O---O distance is about 2.47 Å.〔Barrow, Michael J.; Currie, Murdoch; Muir, Kenneth W.; Speakman, J. Clare; White, David N, J. "Crystal structures of some acid salts of monobasic acids. XVII.
