Question

Is losing hydrogen oxidation or reduction?

Answer 1

• Oxidation- Oxidation is a process in which an atom gains oxygen or loses hydrogen is called oxidation. Also, in oxidation loss of an electron from an atom takes place.
• If lithium loses one electron and forms lithium ion $\left({\mathrm{Li}}^{+}\right)$ that means oxidation is taking place.
• Reduction- Reduction is a process in which an atom gains hydrogen or loses oxygen. Also, in reduction gain of an electron from an atom takes place.
• If oxygen gains two electrons and forms an oxide ion $\left({O_2}^{-}\right)$ that means reduction is taking place.

Hence, losing hydrogen is oxidation.
