Question

In the reaction NaOH (hot and conc.) + Cl $\to$ NaCl + NaClO Change in oxidation state of Cl is :

• A. 0 to -1 and +5
• B. 0 to -1 and +3
• C. 0 to 0 and -1
• D. 0 to -1 and +7

Answer 1

Answer: (A)

0 to -1 and +5

Answer 2

Sodium chlorate, or NaClO3, is the major result of this process. Water and sodium chloride are additional goods. Because chlorine's oxidation state shifted from 0 to -1 in NaCl and to +5 in NaClO3, this reaction is out of balance.

Below is the balanced chemical equation:

6NaOH+Cl2​→5NaCl+NaClO3​+3H2​O

An ion, atom, or specific atoms in a molecule are said to undergo oxidation when they lose electrons or experience a rise in their oxidation state. A reaction when an element interacts with oxygen is another way to explain it. For instance, the chemical interaction between magnesium metal and oxygen to produce magnesium oxide is known as oxidation of magnesium. An oxidizing agent's task is to add oxygen from another material.
