Applications
Food
Sodium acetate may be added to food as a seasoning, sometimes in
the form of sodium diacetate, a one-to-one complex of sodium
acetate and acetic acid, given the E-number E**2. It is often used
to give potato chips a salt and vinegar flavor.
Buffer solution
As the conjugate base of acetic acid, a solution of sodium acetate
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
**6).
