Sodium bicarbonate is a white, crystalline powder commonly used in any laboratory. Sodium bicarbonate is used as a pH buffering agent. The compound can react with both acids and bases. Sodium bicarbonate reacts with the carboxyl groups to give a fast-forming CO2 formation which has been used to test for the presence of carboxylic groups in proteins. Sodium bicarbonate has been observed to significantly decrease serum potassium levels as well as increase blood pH and bicarbonate concentration.
