Question

Which of the following compound acts as an extraordinary oxidising agent?

• A. $H_{2}S{O}_5$
• B. $H_{2}S{O}_4$
• C. $KMn{O}_4$
• D. $F{e}_2{O}_3$

Answer 1

The correct option is A $H_{2}S{O}_5$

Option(a) is correct. Extraordinary oxidising agents are those which oxidises almost all type of substances and in $H_{2}S{O}_5$ the oxidation number of sulfur is +6 as there s a peroxide linkage in the molecule. Thats why, it can accept electrons from other species easily, gets reduced and oxidises almost all substances. Hence, $H_{2}S{O}_5$ acts as an extraordinary oxidising agent
