All mineral acids form hydrogen ions and the conjugate base when dissolved in water.
Mineral acids tend to be very soluble in water and insoluble in organic solvents.
Mineral acids are used in many sectors of the chemical industry as feedstocks for the synthesis of other chemicals, both organic and inorganic.
Mineral acids are also used directly for their corrosive properties.
For example, a dilute solution of hydrochloric acid is used for removing the deposits from the inside of boilers, with precautions taken to prevent the corrosion of the boiler by the acid.
