Question

Which compound acts as oxidising agent only?

• A. $S{O}_2$
• B. $H_{2}S$
• C. $H_{2}S{O}_4$
• D. $HN{O}_2$

Answer 1

The correct option is C $H_{2}S{O}_4$

The oxidising and reducing nature of compound depends upon the,

[1] oxidation number of central atom,

[2] nature of the compound,

here $H_{2}S{O}_4$ is in $+6$ oxidation state which is maximum for sulphur, so it can only accept electrons,this makes it is good oxidiser.
