The redox reaction among the following is

Options

  1. A2 NaOH + Cl 2 → NaCl + NaOCl + H 2 O
  2. Bformation of ozone from atmospheric oxygen in the presence of sunlight
  3. Creaction of [ Co ( H 2 O ) 6 ] C l 3 with AgN O 3
  4. Dreaction of H 2 S O 4 with N a O H

Correct answer

A. 2 NaOH + Cl 2 → NaCl + NaOCl + H 2 O

Step-by-step solution

2 NaOH + Cl 2 → NaCl + NaOCl + H 2 O Here Cl 2 is undergoing oxidation as well as reduction.In rest of these reactions oxidation states are not changing so these are not redox reactions. 3 O 2 → 2 O 3 2NaOH + H 2 S O 4 → N a 2 S O 4 + 2 H 2 O A g N O 3 + NaCl → NaN O 3 + AgCl
