Question

Oxidation is accompanied by an increase in the oxidation state - True or False?

• A. True
• B. False

Answer 1

The correct option is A

True

One of the definitions of oxidation is :

Increase in oxidation number :

$\stackrel{0}{M}g\left(s\right)⟶\stackrel{+2}{M}{g}^{2+}\left(aq\right)+2e^{-}$ (increase in the O.S from 0 to +2)
$\stackrel{-1}{2}C{l}^{-}\left(aq\right)⟶\stackrel{0}{C}{l}_2\left(g\right)+2e^{-}$ (increase in the O.S from -1 to 0)
