The bicarbonate buffer system is one of the chemical buffer systems of the body. How would the bicarbonate buffer system work if sodium hydroxide were added to a solution?

Hydrogen on carbonic acid would dissociate and join the hydroxyl group on the base to form water and sodium bicarbonate.

Explanation:

In the human stomach, the bicarbonate buffer system through the secretion of HCO3- into the inner surface of the stomach helps to equalize the pH of the inside cell of epithelial cells and also functions to neutralize the gastric acid present in the stomach. The bicarbonate buffer system is known as an acid-base homeostatic mechanism and It also helps to support sufficient metabolic functions in the human body.

If sodium hydroxide were added to a solution, sodium hydroxide (strong base) would be converted to sodium bicarbonate (a weak base) in the bicarbonate buffer system.
