Sulphuric acid is considered as the king of chemicals. The prosperity of any country is measured by the amount of sulphuric acid it consumes. Sulphuric acid is, thus, a substance of very great commercial importance as it used practically ine every important industry. This is due to the following properties of sulphuric acid : (a) acidic nature (b) oxidising nature (c) dehydrating nature (d) sulphonation. Concentrated H_2 SO_4 cannot be used to prepare HBr or HI from KBr or KI because it.
