Question

Verify the given reaction is correct or not.
${{H}_{2}}{{O}_{2}}+C{{l}_{2}}\to 2HOCl$
(A) True
(B) False

Answer 1

Hint: The technique to analyse about the given reaction in terms of its true existence has two parameters. One of them is a balanced reaction which is secondary but important and the prime most is the correct products formed when the reactants are reacted.

Complete step by step answer:
Let us look into the reaction carefully,
Here, the reactants are the hydrogen peroxide and chlorine forming product as hypochlorous acid. Though the reaction is balanced, let us see its true existence once before we declare it as a true statement.
Now,
Hydrogen peroxide reacts with chlorine to form hydrogen chloride and oxygen. In this reaction the chlorine is reduced to HCl. The reaction is given as,
${{H}_{2}}{{O}_{2}}+C{{l}_{2}}\to 2HCl+{{O}_{2}}$
Thus, the given reaction about the formation of hypochlorous acid by the reaction of hydrogen peroxide and chlorine; is not true.

Therefore, option (B) False, is correct.

Note: The product formed here i.e. hypochlorous chloride is a weak acid which is actually formed when chlorine dissolves in water. In addition to this, hydrochloric acid is also formed. The reaction is given as,
$C{{l}_{2}}+{{H}_{2}}O\to HOCl+HCl$
Do note that the two parameters are essential to be satisfied to declare a reaction as a true one. Only one cannot help us declare the facts.
