NaHCO3 Mol wt 84.01
A white crystalline powder. It is stable in dry air, but slowly
decomposes in moist air. 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. One g dissolves in 10 ml of water. It is insoluble in
A 1 in 10 solution gives positive tests for Sodium, page 517, and
for Bicarbonate, page 516.
Assay Not less than 99.0% of NaHCO3 after drying.
Ammonia Passes test.
Arsenic (as As) Not more than 3 ppm.
Heavy Metals (as Pb) Not more than 5 ppm.
Insoluble Substances Passes test.
Loss on Drying Not more than 0.25%.
Assay Weigh accurately about 3 g, previously dried over silica
gel for 4 h, dissolve it in 25 ml of water, add methyl orange
TS, and titrate with 1 N sulfuric acid. Each ml of 1 N sulfuric
acid is equivalent to 84.01 mg of NaHCO3.
Is sodium bicarbonate stronger than carbonate?Sodium carbonate is a stronger base than that of the Sodium Bicarbonate. In the human body, sodium bicarbonate plays an important role in reducing the high levels of acid flowing in the bloodstreams. While sodium carbonate mainly works for the various reactions or processes found inside the body.
