NaHCO3
M.W.: 84.01

    Sodium bicarbonate is a commonly used laboratory chemical. The compound can react with both acids and bases, therefore it can be used as a neutralizer. When reacting with bases the compound forms carbonates.
    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.
