Question

Of the four oxyacids of chlorine the strongest
oxidising agent in dilute aqueous solution is

Answer 1

Answer:

HClO4

Explanation:

The strength of the oxy-acids of chlorine increases in the order HClO < HClO2 < HClO3 < HClO4.

Perchloric acid, HClO4, is supposed to be the strongest of all known simple acids.

For the oxy-acids of any non-metal, higher the oxidation number stronger will be the acid. The oxidation states of chlorine in HClO, HClO2, HClO3 and HClO4 respectively are +1, +3, +5, and +7.
