Sodium acetate - Wikipedia
Buffer solution. A solution of sodium acetate (a basic salt of acetic acid) and acetic acid can act as a buffer to keep a relatively constant pH level. This is useful especially in biochemical applications where reactions are pH-dependent in a mildly acidic range (pH 4–6).
Sodium Acetate(CH3COONa) - Structure, Properties, …
Sodium acetate is industrially formed by the reaction of acetic acid with sodium hydroxide in an aqueous solution. CH3COOH + NaOH → CH3COONa + H2O. Chemical reactions of Sodium Acetate – CH3COONa.
How To Make 3 M Sodium Acetate, pH 5.2 - Top Tip Bio
Sodium acetate solution, especially at a 3 M concentration and with a pH of 5.2, is frequently used during DNA and RNA extractions. Since sodium acetate is a salt, its addition enables the precipitation of nucleic acids out of solution.
6.6: Acidic and Basic Salt Solutions - Chemistry LibreTexts
2019年7月12日 · A solution of this salt contains sodium ions and acetate ions. The sodium ion has no effect on the acidity of the solution. However, the acetate ion, the conjugate base of acetic acid, reacts with water and increases the concentration of hydroxide ion: \[\ce{CH3CO2-}(aq)+\ce{H2O}(l)⇌\ce{CH3CO2H}(aq)+\ce{OH-}(aq) \nonumber \]
