The ratio of oxidation states of (Cl) in potassium chloride... | Chemistry | SolveeIt

Question

The ratio of oxidation states of $Cl$ in potassium chloride to that in potassium chlorate is

$\frac{+ 1}{5}$

$\frac{- 1}{5}$

$\frac{- 2}{5}$

$\frac{+ 3}{5}$

Answer

$\frac{- 1}{5}$

Explanation

Solution

$K\overset{+5}{Cl}O_3 \to K\overset{-1}{Cl} + O_2$
Ratio $= \frac{\text{oxidation state Cl in KCl}}{\text{oxidation state of Cl in} KClO_3}$
$= \frac{-1}{5}$
