Question

Consider the following reaction: NaI + 3HOCl --> NaIO3 + 3HCla) Identify the substance oxidizedb) Which species functions as the reducing agentc) Identify the substance reduced

Answer 1

a) NaI

b) NaI

c) HOCl

Step-by-step explanation:

Given reaction:

`\text{NaI}+3\text{HOCl}\rightarrow NaIO_3+3HCl`

a) The substance oxidized:

The substance oxidized is NaI because the oxidation number of iodine in NaI goes from -1 to +5 in NaIO₃

b) The species that functions as the reducing agent:

The species functions as the reducing agent is NaI. This is because the oxidizing agent is the substance reduced and the reducing agent is the substance oxidized

c) The substance reduced:

The substance reduced is HOCl because the oxidation number of chlorine in HOCl goes from +1 to -1 in HCl
