OriginDerived from the chemical family of alkaline salts, produced synthetically from sodium carbonate and carbon dioxide. Manufactured through the Solvay process, where ammonia, brine, and limestone react to generate sodium bicarbonate crystals.
Sodium Bicarbonate is the monosodium salt of carbonic acid with alkalinizing and electrolyte replacement properties. Upon dissociation, sodium bicarbonate forms sodium and bicarbonate ions. Ion formation increases plasma bicarbonate and buffers excess hydrogen ion concentration, resulting in raised blood pH.
