Uses: Hydrochloric Acid is used mainly for the malting of beer, gelatine manufacture, cornflour.
Produced in the stomach to aid digestion.
May have teratogenic properties and may be carcinogenic when mixed with formaldehyde.
Description:Hydrochloric Acid can be prepared commercially by the reaction of sulphuric acid with sodium chloride, or directly by reaction of hydrogen and chlorine gases; the reaction is very exothermic and takes place readily in sunlight or at elevated temperatures.
The major use of HCl is in the manufacture of other chemicals, but other principle applications include metal pickling, gelatine, dyestuffs, casein, pharmaceuticals, synthetic rubber and metal chlorides manufacture.
Large amounts of hydrochloric acid are used in effluent treatment and for the regeneration of ion exchange resins in water treatment.
