\sf{\underline{How to identify a redox reaction}}

Redox Reaction :- The reaction in which the oxidation and reduction takes place simultaneously is called redox reaction.

But for identifying a Redox Reaction the best method is.

\bold</strong><strong>\</strong><strong>r</strong><strong>e</strong><strong>d</strong><strong>{</strong><strong>T</strong><strong>o</strong><strong> </strong><strong>identify</strong><strong> </strong><strong>if</strong><strong> </strong><strong>there</strong><strong> </strong><strong>is</strong><strong> </strong><strong>change</strong><strong> </strong><strong>in</strong><strong> </strong><strong>Oxidation</strong><strong> </strong><strong>number</strong><strong> </strong><strong>or</strong><strong> </strong><strong>not</strong><strong> </strong><strong>}

If their is change in oxidation number the reaction is redox reaction.

If their is no change in oxidation number the reaction is not a oxidation reaction.

From above given four reaction .

Their is change in oxidation number of two reaction.

hence, they are redox reaction.
