# Oxidation and reduction by oxygen

> Oxidation = gain of oxygen (or loss of hydrogen); reduction = loss of oxygen (or gain of hydrogen); the reducing agent takes oxygen away (e.g. CO, H2, C) and the oxidizing agent supplies it.

> [ar-EG] الـ oxidation يعني المادة تكسب oxygen (أو تخسر hydrogen)، والـ reduction يعني المادة تخسر oxygen (أو تكسب hydrogen). الـ reducing agent هو اللي بياخد الـ oxygen من المادة التانية (زي CO و H2 و C)، والـ oxidizing agent هو اللي بيدّيها الـ oxygen.
