Sodium Acetate
USP
C2H3NaO2·3H2O 136.08
Assay
Sodium
Acetate contains three molecules of water of hydration, or is anhydrous. It
contains not less than 99.0 percent and not more than 101.0 percent of
C2H3NaO2, calculated on the dried basis.
Packaging and storage Preserve in tight containers.
Labeling
Label it
to indicate whether it is the trihydrate or is anhydrous. Where Sodium
Acetate is intended for use in hem dialysis, it is so labeled.
Identification A
solution responds to the test for Sodium and for Acetate.
pH: between 7.5 and
9.2, in a solution in carbon dioxide-free water containing the equivalent of
30 mg of anhydrous sodium acetate per mL.
Loss on drying Dry
at 120 to constant weight: the hydrous form loses between 38.0% and 41.0% of
its weight, and the anhydrous form loses not more than 1.0% of its weight.
Insoluble matter Dissolve the equivalent of 20 g of anhydrous sodium acetate in 150 mL of
water, heat to boiling, and digest in a covered beaker on a steam bath for 1
hour. Filter through a tarred filtering crucible, wash thoroughly, and dry at
105 : the weight of the residue does not exceed 10 mg (0.05%).
Chloride
A portion
equivalent to 1.0 g of anhydrous sodium acetate shows no more chloride than
corresponds to 0.50 mL of 0.020 N hydrochloric acid (0.035%).
Sulfate
A portion
equivalent to 10 g of anhydrous sodium acetate shows no more sulfate than
corresponds to 0.50 mL of 0.020 N sulfuric acid (0.005%).
Calcium and magnesium To 20 mL of a solution containing the equivalent of 10 mg of anhydrous
sodium acetate per mL add 2 mL each of 6 N ammonium hydroxide, ammonium
oxalate TS, and dibasic sodium phosphate TS: no turbidity is produced within
5 minutes.
Potassium
Dissolve
the equivalent of 3 g of anhydrous sodium acetate in 5 mL of water, add 1N
acetic acid drop wise until the solution is slightly acidic, and then add 5
drops of sodium cobalt nitrite TS: no precipitate is formed.
Aluminum: (where it
is labeled as intended for use in hem dialysis) the limit is 0.2΅ =g per g.
Heavy metalsthe
limit is 0.001%.
Organic volatile
impurities: meets the requirements.

TESTS
Solution S
Dissolve 10.0 g in carbon
dioxide-free water prepared from
distilled water R
and dilute to 100 ml
100 ml with the same solvent.
Appearance of
solution
Solution S is clear and colourless.
pH
7.5 to 9.0.
Dilute 5 ml of solution S to 10 ml with carbon
dioxide-free water.
Reducing substances
Dissolve 5.0 g in 50 ml of water,
then add 5 ml of dilute sulphuric
acid and 0.5 ml of 0.002 M potassium
permanganate. The pink colour persists
for at least 1 h. Prepare a blank in the same manner but without the
substance to be examined.
Chlorides
Maximum 200 ppm.
Sulphates
Maximum 200 ppm.
Aluminium
Maximum 0.2 ppm, if intended for use in the
manufacture of dialysis solutions.

C2H3NaO2 Formula wt,
anhydrous 82.03
C2H3NaO2·3H2O Formula wt,
trihydrate 136.08
DESCRIPTION
Sodium Acetate occurs as
colorless, transparent crystals or as a granular, crystalline or white
powder. The anhydrous form is hygroscopic; the trihydrate effloresces in
warm, dry air. One gram of the anhydrous form dissolves in about 2 mL of
water; 1 g of the trihydrate dissolves in about 0.8 mL of water and in about
19 mL of alcohol.
Function: Buffer.
REQUIREMENTS
Identification: A 1:20 aqueous solution gives positive tests for
Sodium and for Acetate.
Assay: Not less than
99.0% and not more than 101.0% of C2H3NaO2 after drying.
Alkalinity Anhydrous: Not more than 0.2%; Trihydrate: Not more than 0.05%.
Lead: Not more than
2 mg/kg.
Loss on Drying: Anhydrous: Not more than 1.0%; Trihydrate: Between 36.0% and
41.0%.
Potassium Compounds: Passes test.
