Sodium bicarbonate (HCO-3) present in pancreatic juice neutralises the acidity of the chyme to prevent damage to the walls of the duodenum and provides a neutral pH environment for the digestion of chyme.

Q. Which of the following anions neutralises the acidic $p H$ of the chyme that enters into the duodenum from the stomach?

$H_{2} P O_{4}^{-}$

$H S O_{4}^{-}$

$H C O_{3}^{-}$

$C H_{3} CO O^{-}$

Sodium bicarbonate $(H C O_{^{3}}^{-}$ ) present in pancreatic juice neutralises the acidity of the chyme to prevent damage to the walls of the duodenum and provides a neutral $p H$ environment for the digestion of chyme.
