The acetate anion, [C2H3O2]-,
is a carboxylate and is the conjugate base of acetic acid. The acetate ion
is formed by the deprotonation of acetic acid:
CH3COOH ? CH3COO- + H+

Sodium acetate is inexpensive, and is usually
purchased from chemical suppliers, instead of being synthesized in the
laboratory. It is sometimes produced in a laboratory experiment by the
reaction of acetic acid with sodium carbonate, sodium bicarbonate, or
sodium hydroxide to name a few bases which contain sodium.
CH3-COOH + Na+[HCO3]- 
CH3-COO- Na+ + H2O + CO2 |
|
It can be prepared by reacting a
potassium-containing base such as potassium hydroxide or potassium
carbonate with acetic acid: 2CH3COOH + K2CO3
2CH3COOK + CO2 + H2O This sort of
reaction is known as an acid-base neutralization reaction. Potassium
acetate is the salt that forms along with water as acetic acid and
potassium hydroxide are neutralized together.Conditions/substances to avoid are: moisture, heat, flames, ignition sources, and strong oxidizing agents. |
