The ratio of oxidation states of Cl\mathrm{Cl} in potassium chloride to that in potassium chlorate is

Options

  1. A+15\frac{+1}{5}
  2. B−15\frac{-1}{5}
  3. C−25\frac{-2}{5}
  4. D+35\frac{+3}{5}

Correct answer

B. −15\frac{-1}{5}

Step-by-step solution

KCl\mathrm{KCl} x & =-1 KClO3\mathrm{KClO}_{3} potassium chloride +1+x−6=0+1+x-6=0 x=+5 potassium chlorate. ∴\therefore Ratio of oxidation state of Cl=−15\mathrm{Cl}=\frac{-1}{5}
