Which one of the following is an example of disproportionation reaction?
Options
- Aaligned & 3 Cl ₂(g)+6 OH ⁻(a q) ClO ₃⁻(a q)+5 Cl ⁻(a q) & +3 H ₂ O (l) & aligned
- BAg ²⁺( aq )+ Ag ( s ) 2 Ag ⁺( aq )
- CZn (s)+ CuSO ₄(a q) Cu (s)+ ZnSO ₄(a q)
- D2 KClO ₃( ~s ) 2 KCl ( s )+3 O ₂( ~g )
Correct answer
A. aligned & 3 Cl ₂(g)+6 OH ⁻(a q) ClO ₃⁻(a q)+5 Cl ⁻(a q) & +3 H ₂ O (l) & aligned
Step-by-step solution
A reaction in which the same species is simultaneously oxidised as well as reduced is called a disproportionation reaction.
