Activity coefficient of aqueous sodium bicarbonate

Sodium bicarbonate

Major uses Sodium bicarbonate is a main constituent of baking soda/powder. Baking powder is composed of 30% of sodium bicarbonate, with cornstarch, sodium aluminium sulfate, calcium acid phosphate, and calcium sulfate [1]. Sodium bicarbonate may be an ingredient of folk remedies containing turpentine, castor oil, lemon and sugar. It is also added to mouthwashes and dentifrices to prevent dental...

Sodium bicarbonate revisited.

Sodium-coupled bicarbonate transporters.

Together, the Na(+)-coupled HCO(3)(-) transporters and the AE family of anion exchangers (i.e., Cl-HCO3 exchangers) comprise the bicarbonate transporter (BT) superfamily. Virtually all BTs are important for the regulation of intracellular pH (pH(i)) in cells throughout the body. Specific BTs also play roles in cell-volume regulation, as well as for the transport of salt and/or acid-base equival...

Sorption properties of sodium bicarbonate

Introduction From the point of view of different technological processes, the knowledge of parameters describing the structure of sorbents, such as surface area or pore size distribution play an important role for application them in chemical, cement industries, or modification of mineral raw materials. The sorption properties are determined by surface area, what binds with surface energy and r...

The Activity Coefficient of Sodium in Striated Muscle Fibers

Dear Sir: The statement by Brinley (1968) that for striated muscle fibers from the giant barnacle " . . . one can calculate an activity coefficient for sarcoplasmic sodium of ca. 0.5-0.6 which is not greatly different from what one might expect from a mixed salt solution having the composition of the sarcoplasm (0.65-0.75)" requires some comment. This calculation was made by dividing the averag...
