What are some uses for hydrochloric acid?

Hi,

Hydrochloric acid is used for:

Regeneration of ion exchangers
pH Control and neutralization
Pickling of steel (to remove rust or iron oxide scale from iron or steel)
Production of inorganic and organic compounds
Leather processing, household cleaning, and building construction
Also, a way of stimulating oil production is by injecting hydrochloric acid into the rock formation of an oil well, dissolving a portion of the rock, and creating a large-pore structure

Hope that helps.

Your stomach uses it to aid in digesting your food.
The pharmaceutical industry uses it to make medications water soluable
It is good for cleaning tile grout, concrete, and is used in swimming pools.
