Question

In the reaction 3Cl2 +6NaOH ----------- NaClO3 + 5NaCl + 3H2O , which element loses as well as gain electrons ?

Answer 1

It is a disproportion reaction Cl2 - loses 0 electrons and gained 0 electrons, NaClO3 gains

5 electrons and NaCl loses 1 electron

Answer 2

Answer: $Cl_{2}$ undergoes redox reaction so Cl is the element that loses and gains electrons.

Disproportionation Reaction: A disproportionation reaction is a chemical process in which a molecule experiences both oxidation and reduction.

Oxidation: The loss of an electron during a reaction is called an oxidation reaction.

Reduction: The gain of an electron during a reaction is called a reduction reaction.

Explanation:

Step 1: The reaction is:

$3Cl_2 + 6NaOH -- > NaClO_3 + 5NaCl+ 3H_2O\\\hspace{20} 0 \hspace{100}+5 \hspace{30}-1$

Number of electrons gained and lost during the reaction

Step 2: Therefore, from the reaction, we can see that Cl is the only element that has gained and lost an electron during the whole reaction.
