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…

Sodium phosphate is a reagent with very high buffering capacity that is widely used in molecular biology, biochemistry, and chromatography. Sodium phosphate occurs in several forms: monobasic (NaH2PO4), dibasic (Na2HPO4), and tribasic (Na3PO4). Most neutral sodium phosphate buffer solutions consist…

Sodium metabisulfite is an antioxidant reducing agent, with antimicrobial and antifungal properties. Gastric tissue studies report that sodium metabisulfite can augment lipid peroxidation and apoptosis in a dose-dependent manner. Sodium metabisulfite is used as an active ingredient in campden…

Potassium phosphate is a reagent with high buffering capacity. It occurs in several forms: monobasic, dibasic and tribasic. Most pH neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH. Potassium…
