In the reaction 3 Br ₂+6 CO ₃²⁻+3 H ₂ O 5 Br ⁻+ BrO ₃⁻+6 HCO ₃⁻
Options
- ABromine is oxidised and carbonate is reduced.
- BBromine is reduced and water is oxidised.
- CBromine is neither reduced nor oxidised.
- DBromine is both reduced and oxidised.
Correct answer
D. Bromine is both reduced and oxidised.
Step-by-step solution
aligned 3 Br ₂+6 CO ₃²⁻+3 H ₂ O & 5 Br ⁻ &+ BrO ₃⁻+6 HCO ₃⁻ aligned O.N. of Br ₂ changes from 0 to -1 and +5 , hence it is reduced as well as oxidised.
