Question

Assume the concentration of stomach acid is 0.10M and theneutralizing capacity of the acid is 0.013 mol/g, calculate the volumeof stomach acid needed to neutralize 1.0 g antacid tablet.

Answer 1

Given that the concentration of stomach acid is 0.10M and the

1. Neutralizing capacity of the acid is 0.013 mol/g,

Therefore number of moles required to neutralize 1 gram of antiacid is , n = 0.013 mol

2. Concentartion of an acid is 0.1M

3. We know that C = n/V

∴ Volume = n/C

= 0.013mol/g/ 0.1M

=0.13 L

or Volume = 130ml
