Question

“Oxidation” is a process which involves loss of electrons". Is the statement true or false?

• A. True
• B. False

Answer 1

The correct option is A True

• The process of oxidation involves the loss of one or more electrons from an atom or ion. In the oxidation process, the oxidation number of a substance increases by the loss of electrons.
• Example, Iron(III) ion (Fe³⁺) is formed by the loss of one electron (${\mathrm{e}}^{-}$) from Iron(II) ion (Fe²⁺).

${\mathrm{Fe}}^{2+}\left(\mathrm{aq}\right)\to {\mathrm{Fe}}^{3+}\left(\mathrm{aq}\right)+{\mathrm{e}}^{-}$

• The oxidation number of Iron (Fe) is +2 in Fe²⁺ and +3 in Fe³⁺. Therefore, the loss of electrons results in an increase in the oxidation number of Fe which implies that oxidation takes place.
• Hence, the statement is true. Oxidation is a process that involves the loss of electrons.
