Hot conc. `H_(2)SO_(4)` acts as molderately strong oxidising agent It oxidises both metals and non - metals. Which of the following element is oxidised by conc. `H_(2)SO_(4)` into two gaseous products. ?

Options

A. Cu
B. S
C. C
D. Zn

Answer

C

Explanation

`H_(2)SO_(4)` is a moderately strong oxidising agent which oxidises both metals and non - metals as shown below
`Cu+2H_(2)SO_(4)(conc)to CuSO_(4)+SO_(2)+2H_(2)O`
`S+2H_(2)SO_(4)(conc)to3SO_(2)+2H_(2)O`
While carbon on oxidation with `H_(2)SO_(4)` produces two types of oxides `CO_(2)` and `SO_(2)`.
`C+2H_(2)SO_(4)(conc)toCO_(2)+2SO_(2)+2H_(2)O`
