Question

Consider the following reaction: NaI + 3HOCl --> NaIO3 + 3HClWhich species functions as the oxidizing agenta) HClb) NaIc) NaIO3d) HOCL

Answer 1

Answer: Option D

Given the reaction :

`\text{NaI +3HOCl }\Rightarrow NaIO_3\text{ + 3HCL }`

we can conclude that :

• Chlorine is reduced in this reaction

,

• oxidation state of chlorine in (HOCl) = +1, whereas

,

• oxidation state of chlorine in HCl = -1

• This means that HOCl is the oxidising agent.
