Sodium bicarbonate solution has a strong alkaline, is the role of bicarbonate ion, and because the bicarbonate ion can decompose hydrogen ions, is a weak acidic ion, so encountered with some of the strong bases, such as calcium hydroxide can be produced calcium carbonate and water and sodium carbonate. This is the basic meaning of chemistry.

In biology, it has its special significance in body fluids, it plays a buffering role, can neutralize the excessive acidic products in body fluids, to maintain the acid-base balance of body fluids. In life it is also a very good can be used in fire extinguishers as a raw material to produce carbon dioxide. In first aid, it can be used to clean patients with strong acid burns.

The presence of sodium and bicarbonate ions is positive in all pathways of the body's fluid circulation.

Sodium bicarbonate solution can be very tough and versatile in nature
