Q10 / 125 · BITSAT 2014 · Chemistry
The ratio of oxidation states of $\mathrm{Cl}$ in potassium chloride to that in potassium chlorate is
- A$\frac{+1}{5}$
- Correct answerB$\frac{-1}{5}$
- C$\frac{-2}{5}$
- D$\frac{+3}{5}$
Solution
\mathrm{KCl} x & =-1 & \mathrm{KClO}_{3}
potassium chloride $+1+x-6=0$
$$
x=+5
$$
potassium chlorate.
$\therefore$ Ratio of oxidation state of $\mathrm{Cl}=\frac{-1}{5}$
Hence, the correct answer is option: 'B'.
