DEFINITION
Trisodium
2-hydroxypropane-1,2,3-tricarboxylate dihydrate.
Content
99.0 per cent to 101.0
per cent (anhydrous substance).
CHARACTERS
Appearance
White or almost white,
crystalline powder or white or almost white, granular crystals, slightly
deliquescent in moist air.
Solubility
Freely soluble in
water, practically insoluble in ethanol (96 per cent).
IDENTIFICATION
A. To 1 ml of solution
S (see Tests) add 4 ml of water. The solution gives the reaction
of citrates.
B. 1 ml of solution S
gives reaction of sodium.
TESTS
Solution S
Dissolve 10.0 g in carbon dioxide-free water R
prepared from distilled water R and dilute to 100 ml with the same solvent.
Appearance of
solution
Solution S is clear and colourless.
Acidity or
alkalinity
To 10 ml of solution S
add 0.1 ml of phenolphthalein solution. Not more than 0.2 ml of
0.1M hydrochloric acid or 0.1 M sodium hydroxide is
required to change the colour of the indicator.
Readily
carbonisable substances
To 0.20 g of the
powdered substance to be examined add 10 ml of sulphuric acid and
heat in a water-bath at 90 ± 1 °C for 60 min. Cool rapidly. The solution
is not more intensely coloured than reference solution.
Chlorides
Maximum 50 ppm.
Oxalates
Maximum 300 ppm.
Sulphates
Maximum 150 ppm.
Heavy metals
Maximum 10 ppm.
Water
11.0 per cent to 13.0
per cent, determined on 0.300 g. After adding the substance to be examined, stir for 15
min before titrating.

Sodium Citrate is anhydrous or contains two molecules of water of hydration. It contains not less than 99.0 percent and not more than 100.5 percent of C6H5Na3O7, calculated on the anhydrous basis.
Identification—
A: A solution (1 in 20) responds to the tests for Sodium and for
Citrate.
B: Upon ignition, it
yields an alkaline residue which effervesces when treated with 3 N
hydrochloric acid.
Alkalinity— A solution
of 1.0 g in 20 mL of water is alkaline to litmus paper, but after the
addition of 0.20 mL of 0.10 N
sulfuric acid no pink color is produced by 1 drop of phenolphthalein TS.
Water— Dry it at 180
for 18 hours: the anhydrous form loses not more than 1.0%, and the
hydrous form between 10.0% and 13.0%, of its weight.
Tartrate— the limit is
0.001%.

DESCRIPTION
Sodium Citrate occurs
as colorless crystals or as a white, crystalline powder. It is anhydrous
or contains two molecules of water of crystallization. One gram of the
dihydrate dissolves in 1.5 mL of water at 25° and in 0.6 mL of boiling
water. It is insoluble in alcohol.
REQUIREMENTS
Identification: A 1:20 aqueous solution gives positive tests for
Sodium and for
Citrate.
Assay: Not less
than 99.0% and not more than 100.5% of C6H5Na3O7, calculated on the
anhydrous basis.
Alkalinity: Passes test.
Lead: Not more
than 2 mg/kg.
Water: Anhydrous: Not more than 1%;
Dihydrate: Between 10.0% and
13.0%.
