Sodium carbonate

Sodium carbonate, anhydrous is the sodium salt of carbonic acid. Widely used reagent in biochemistry and molecular biology research, most often as a buffer component in applications such as chromatography, capillary electrophoresis, and enzyme catalysis. Ideal for the isolation of cell membranes, membrane proteins, and hydrophobic proteins. In chemistry, used as an electrolyte, acting as a good conductor in electrolysis. Because it is solid, air-stable, and easy to weigh, sodium carbonate is useful as a primary standard for acid-base titrations.
