Chlorine upon reaction in cold NaOH yields:
Correct answer: A. NaCl, NaClO, H2O
- A. NaCl, NaClO, H2O
- B. NaCl , NaClO3 , H2O
- C. NaClO , NaClO3, H2O
- D. NaCl , H2O
Explanation
Cold dilute sodium hydroxide and chlorine gas reaction is disproportionation. Chlorine gas is oxidized and reduced to OCl- ion and Cl- ion respectively.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
