Chlorine oxidises iodine to periodic acid in water

Vedclass · Answer

(B) The correct answer is $B$. $1$. Chlorine $(Cl_2)$ oxidises ferrous salts $(Fe^{2+})$ to ferric salts $(Fe^{3+})$ in acidic medium: $2Fe^{2+} + Cl_2 \rightarrow 2Fe^{3+} + 2Cl^-$. This statement is correct. $2$. Chlorine oxidises iodine $(I_2)$ to iodic acid $(HIO_3)$,not periodic acid $(HIO_4)$,in the presence of water: $I_2 + 5Cl_2 + 6H_2O \rightarrow 2HIO_3 + 10HCl$. Thus,statement $B$ is incorrect. $3$. Chlorine acts as a bleaching agent due to the oxidation of coloured substances by nascent oxygen: $Cl_2 + H_2O \rightarrow 2HCl + [O]$. This statement is correct. $4$. Chlorine is manufactured by Deacon's process,which involves the oxidation of hydrogen chloride gas by atmospheric oxygen in the presence of $CuCl_2$ as a catalyst: $4HCl + O_2 \xrightarrow{CuCl_2} 2Cl_2 + 2H_2O$. This statement is correct.
