Working of Antacids: If The Antacid Contains Nahco Then The Reactions That Occur in The Stomach Are

When an antacid containing NaHCO3 is consumed, three reactions occur in the stomach: 1. Na+ and HCO3- ions react with H+ and Cl- ions from hydrochloric acid to form NaCl and H2CO3. 2. The H2CO3 formed rapidly decomposes into water and carbon dioxide gas. 3. The excess Na+ and HCO3- ions are absorbed by the small intestine walls as food passes through.

Working Of Antacids

If the antacid contains NaHCO3 then the reactions that occur in the
stomach are:

Na+ + HCO3 + H+ + Cl-

H2CO3

NaCl + H2CO3

H2O + CO2

The excess Na and HCO3- ions are absorbed by the walls of the small intestines as
the food passes through

The H2CO3 formed during the reaction decomposes rapidly to form water and carbon
dioxide gas.

INTRODUCTION
It is well known that
the food we take
undergoes a series of
complex reactions
within
the
body which constitute
what we call digestion
and metabolism .These
reactions are
catalyzed by enzymes
which are very specific
in their action and can
function properly
only when the pH of the
medium is within a
specific range.
Some enzymes
require mildly alkaline
conditions while others
operate only in weakly
acidic conditions. In the
stomach dilute
hydrochloric acid is
secreted and it provides
mildly acidic conditions
required for the
functioning of protein
digesting enzymes in
the
stomach.

Gastric acid is a
digestive fluid, formed
in the stomach. It has
a pH of 1.5 to 3.5
and is composed of
0.5 % hydrochloric
acid (HCl). It is
produced by cells
lining
the

Aim :
To analyze the given
samples of commercial
antacids by determining
the amount of
Hydrochloric Acid they
can neutralize.
