Plz mark me as brainliest

Answer 2

Answer:

The equivalent mass of $ClO_{3}$ is $\frac{2M}{3}$ and option 1 is correct.

Explanation:

As per the data given in the question

We have to calculate the equivalent mass of $ClO_{3}$

As per the question

It is given that

$ClO_{3}^-$  → $Cl^{-}+ClO_{4}^-$

where as M= molar mass of $ClO_{3}$

This reaction is oxidized reaction.

In this reaction the oxidation state of Cl is $ClO_{3}^-$ is +5 which is decreasing 0.In $Cl_{2}$ or +4 in $ClO_{2}$.Means Cl is reduced and acting as oxidized agent.

And oxidation state of Cl is $Cl^{-} is -1$

In $ClO_{2}$ ,Means Cl is oxidized and acting as reducing agent.

$ClO_{3}^-$ → $Cl^{-}$  where n=6

$ClO_{3}^-$ → $ClO_{4}^-$ where n=2

we know n= $\frac{n_{1}n_{2} }{n_{1}+n_{2} }$ = $\frac{12}{8}=\frac{3}{2}$

Equivalent weight = $\frac{m}{n}=\frac{m}{\frac{3}{2} }$ = $\frac{2m}{3}$

Hence, the equivalent mass of $ClO_{3}$ is $\frac{2M}{3}$ and option 1 is correct.
