Sodium Bicarbonate as per BP
Specifications
Sodium Hydrogen Carbonate
NaHCO3
84.0ıı144-55-8
Action and use
Antacid; used in treatment of electrolyte deficiency.
DEFINITION
Content
99.0 per cent to 101.0 per cent.NaHCO3
CHARACTERS
Appearance
White or almost white, crystalline powder.
Solubility
Soluble in water, practically insoluble in ethanol (96
per cent). When heated in the dry state or in solution, it gradually changes
into sodium carbonate.
IDENTIFICATION
A. To 5 ml of solution S add 0.1 ml of phenolphthalein solution. A pale pink colour is produced. Heat; gas is
evolved and the solution becomes red.
B. It gives the reaction of carbonates and
bicarbonates.
C. Solution S gives reaction of sodium.
TESTS
Solution S
Dissolve
5.0 g in 90 ml of carbon dioxide-free water and dilute to 100.0 ml with
the same solvent.
Appearance of solution
Solution S
is clear and colourless.
Carbonates
The pH of
freshly prepared solution S is not greater than 8.6.
Chlorides
Maximum 150
ppm.
Sulphate
Maximum 150
ppm.
Ammonium
Maximum 20
ppm.
Arsenic
Maximum 2
ppm, determined on 0.5 g.
Calcium
Maximum 100
ppm.
To a
suspension of 1.0 g in 10 ml of distilled water add hydrochloric acid
until neutral and dilute to 15 ml with distilled water.
Iron
Maximum 20
ppm..
Heavy
metals
Maximum 10

Carbonic acid monosodium salt.
Monosodium carbonate
Sodium Bicarbonate contains not less than 99.0 percent and not more than 100.5 percent of NaHCO3, calculated on the dried basis.
Labeling— Where Sodium Bicarbonate is intended for use in
hem dialysis, it is so labeled.
Identification—
A solution of it meets the requirements of the
tests for Sodium 191 and for Bicarbonate.
Loss on drying— Dry about 4 g, accurately weighed, over silica
gel for 4 hours: it loses not more than 0.25% of its weight.
Insoluble substances— Dissolve 1 g in 20 mL of water: the resulting
solution is complete and clear.
Carbonate (where it is
labeled as intended for use in hem dialysis)— The limit of carbonate is not more than 0.23%. to be determined
as per tests defined.
Normal carbonate—
Add 2.0 mL of 0.10 N hydrochloric acid and 2
drops of phenolphthalein TS to 1.0 g of Sodium Bicarbonate, previously dissolved
without agitation in 20 mL of water at a temperature not exceeding 15 : the
solution does not assume more than a faint pink color immediately.
Chloride—:
a 0.35-g portion shows no more chloride than corresponds to 1.48 mL of 0.0010 N
hydrochloric acid (0.015%).
Limit of sulfur compounds—
To pass the test
Aluminum
(where it is labeled as intended for use in
hem dialysis)— The limit is 2 µg per g.
Arsenic—
The limit is 2 µg per g.
Calcium and magnesium
(where it is labeled as intended for use in
hem dialysis)
— the percentage of Ca in the specimen limit is
0.01%.
— the percentage of Mg in the specimen the limit
is 0.004%.
Copper
(where it is labeled as intended for use in
hem dialysis)— Cu in the specimen
the limit is 1 µg per g.
Iron
(where it is labeled as intended for use in
hem dialysis)— not more than 5µg per
g.
Heavy metals—the limit is 5
µg per g.
Limit of ammonia—
to pass the test
Limit of organics—
(where it is labeled as intended for use in
hem dialysis)— To pass the test

Formula wt 84.01
INS:
500(ii) CAS: [144-55-8]
DESCRIPTION
Sodium
Bicarbonate occurs as a white, crystalline powder. It is stable in dry air, but
it slowly decomposes in moist air. One gram dissolves in 10 mL of water. It is
insoluble in alcohol. Its solutions, when freshly prepared with cold water
without shaking, are alkaline to litmus. The alkalinity increases as the
solutions stand, are agitated, or are heated.
Function
pH control agent; leavening agent.
REQUIREMENTS
Identification A 1:10 aqueous solution gives positive tests for
Sodium
and for Bicarbonate,
Assay
Not less than 99.0% and not more than 100.5% of NaHCO3 after drying.
Ammonia
Passes test.
Insoluble Substances Passes test.
Lead Not more than 2 mg/kg.
Loss on
Drying Not more than 0.25%.

Refresh Yourself with these pleasant thoughts.
I shall pass through this world, but once. If therefore, there is any good that I can do, or if there is any favour that I can show to a fellow human being, let me do it now. Let me not defer or neglect it. For I shall not tread this way again.
If you want your work to be done well, then go to a busy man. The other one has no time.
