Question

The $E^{o}$ values of redox complex of halogens are given. Based on these values mark the correct statement.

${E^{o}}_{I_{2}/I^{-}} = + 0.54V,{E^{o}}_{Br_{2}/Br^{-}} = + 1.08V;$

${E^{o}}_{Cl_{2}/Cl^{-}} = + 1.36V,$

• A. Chlorine can displace bromine and iodine from their satl solutions.
• B. Chlorine can only displace iodine from its salt solution.
• C. Bromine can displace chlorine from its salt solution.
• D. Iodine can displace chlorine and bromine from their salt solutions.

Answer 1

Answer: (A)

Chlorine can displace bromine and iodine from their satl solutions.

Answer 2

: Since chlorine has higher reduction potential than bromine and iodine so it can displace them from their salt solutions.

$2NaI + Cl_{2} \rightarrow 2NaCl + I_{2}$

$2NaBr + Cl_{2} \rightarrow 2NaCl + Br_{2}$
