![The reactions accompanied by a change of atom oxidation number of elements are called oxidation-reduction reactions.](/_ipx/f_webp&q_80&fit_contain&s_1440x1080/imagesDir/jpg/12923/slide-1.jpg)
The reactions accompanied by a change of atom oxidation number of
elements are called
oxidation-reduction reactions.

![The particles which accept electrons are called oxidizers. The particles which donate electrons are called reducers.](/_ipx/f_webp&q_80&fit_contain&s_1440x1080/imagesDir/jpg/12923/slide-2.jpg)
The particles which accept electrons are called oxidizers.
The particles which
donate electrons are called reducers.
Слайд 4
![Fе2+ + Се4+ ↔ Fе3+ + Се3+ Oxidized and reduced](/_ipx/f_webp&q_80&fit_contain&s_1440x1080/imagesDir/jpg/12923/slide-3.jpg)
Fе2+ + Се4+ ↔ Fе3+ + Се3+
Oxidized and reduced forms of
one substance involved in the half-reaction compose redox couple:
Fе2+ – ē ↔ Fе3+
Се4+ + ē ↔ Се3+

![A conductor (metal) immersed into a solution of its salt](/_ipx/f_webp&q_80&fit_contain&s_1440x1080/imagesDir/jpg/12923/slide-5.jpg)
A conductor (metal) immersed into a solution of its salt is
called
electrode
Potential difference arising on the electrode-solution interfase is called electrode potential
