Alternate Names Sodium Hydrogen Carbonate; Baking Soda; Carbonic acid monosodium salt; Monosodium carbonate
Application Notes Sodium bicarbonate is broadly used as a physiological buffer in cell culture applications. The pKa for bicarbonate <-> carbonic acid reaction is 6.4 The pKa for bicarbonate <-> carbonate reaction is 10.3. Sodum bicarbonate has two pKas, 6.4 and 10.3. The compound can react with both acids and bases, therefore it can be used as a neutralizer. Sodium bicarbonate may be used to remove or wash acidic impurities from a crude liquid to yield a purer sample. Sodium bicarbonate reacts with the carboxyl groups to give a fast-forming and effervescent CO2 formation which has been used to test for the presence of carboxylic groups in proteins.
