Hydrochloric acid
HCl

Does Hydrochloric acid Same as Stomach acid?

Stomach acid and hydrochloric acid (HCl) are often used interchangeably, but there's a subtle difference:

Stomach Acid:

Refers to the acidic digestive fluid produced by the stomach
Composed of:
Hydrochloric acid (HCl)
Pepsin (enzyme)
Gastric amylase (enzyme)
Gastric lipase (enzyme)
Bile salts
Mucus
pH level: 1.5-3.5

Hydrochloric Acid (HCl):

A specific chemical compound (HCl)
A strong acid with a pH level of 0-1
Primary component of stomach acid (0.5-1.5% concentration)
Essential for:
Protein digestion
Killing bacteria and pathogens
Activating digestive enzymes

Key differences:

1. Stomach acid is a mixture, while HCl is a single compound.
2. Stomach acid has a higher pH level than pure HCl.
3. HCl is a key component of stomach acid, but not the only one.
