Question

Reaction of chlorine with sodium hydroxide is called :

• A. disproportionation reaction
• B. neutralization reaction
• C. acidification reaction
• D. hydrolysis

Answer 1

The correct option is A disproportionation reaction

Many non-metals react with bases to form salts. One atom of chlorine gains an electron and is converted into chloride ion Cl and the other loses an electron and forms hychlorite ion, $ClO$. This is a good example of a disproportionation reaction. A disproportionation reaction is one in which a single substance is both oxidised and reduced.
