Explain the oxidising property of sulphuric acid .

Explanation

Oxidising property of `H_(2)SO_(4)`:
Sulphuric acid is an oxidising agent as it produces nascent oxygen as shown below.
`H_(2)SO_(4) rarr underset(" nascent oxygen")(H_(2)O+SO_(2)+(O))`
Sulphuric acid oxidises elements such as carbon, sulphur and phosphorus. It also oxides bromide and iodide to bromine and iodine respectively.
`C+2H_(2)SO_(4) rarr 2SO_(2)+2H_(2)O+CO_(2)`
`S+2H_(2)SO_(4)rarr 2SO_(2)+2H_(2)O`
`P_(4)+10H_(2)SO_(4)rarr4H_(3)PO_(4)+10SO_(2)+4H_(2)O`
`H_(2)S+H_(2)SO_(4) rarr SO_(2)+2H_(2)O+S`
`H_(2)SO_(4)+2HI rarr SO_(2)+H_(2)O+I_(2)`
`H_(2)SO_(4)+2HBr rarr 2H_(2)O+Br_(2)`
