Commonly known as mineral acids, inorganic acids are the ones that have been synthesized from one or more organic compounds, and are distinguished by their characteristic chemical behavior of furnishing hydrogen ions on dissolution in water. Mineral acids have a tendency of being highly soluble in water and sparingly soluble to being totally insoluble in organic solvents, and can be either oxygen-less or have oxygen in their chemical structure, in which case they are called oxo-acids. Depending upon the number of ions (hydrogen ions in particular) produced by them in their aqueous form, they can be classified as either monobasic, di-basic or tri-basic acids.
1) Sulphuric Acid is one of the most common inorganic acids which is dibasic, and is used in a wide range of laboratory as well as industrial processes like metal & oil refining, getting rid of corrosion and synthesis of fertilizers.
2) Nitric Acid, a monobasic oxo-acid, is widely used as a common laboratory agent and is used in production of dyes, fertilizers and explosives (A prominent example being TNT).
3) Dilute solutions of Hydrochloric Acid are used in removal of deposits from the insides of boilers and reaction vessels, a process that is commonly known as descaling.
4) Phosphporic Acid, which is a well known tri-basic oxo acid, is one of the major substrates that is used in production of fertilizers, a process which accounts for over 90% of its consumption.
