Question

Give me examples of oxidation, reduction and redox reactions separately.?

Answer 1

OXIDATION

• When the soft insides of fruit are exposed to oxygen in the air, they become oxidized, causing them to break down and turn brown. The process is very similar to rusting; oxygen steals electrons from atoms and compounds. The unoxidized form of these compounds is different from the oxidized form that is, unfortunately, unappealing to eat.

REDUCTION

copper oxide and magnesium to yield copper and magnesium oxide:

CuO + Mg → Cu + MgO

REDOX REACTION

$f2 -2e {}^{ - } = > 2f {}^{ - } \\ h2 + f2 = > 2hf$

Answer 2

Solution:

Oxidation:-

The addition of oxygen to a substance is called oxidation or the removal of hydrogen from a substance is called oxidation.

For example:- Heating magnesium ribbon in air is a oxidation reaction.

$\sf 2Mg(s) + O_{2} \to 2MgO(s)$

$\rule{100}{5}$

Reduction:-

The addition of hydrogen to a substance is called reduction or the removal of oxygen from a substance is called reduction.

For example:- Nitrogen reacts with hydrogen to form ammonia and here nitrogen gets reduced to ammonia.

$\sf N_{2}(g) + 3H_{2}(g) \to 2NH_{3}(g)$

$\rule{100}{5}$

Redox:-

In these reactions, electrons are transferred from one reactant to another. So, simply put, electrons are lost from one substance and gained by another.

Oxidation refers to the loss of electrons from a substance, while reduction refers to the gain of electrons by a substance.

For example:- In the reaction between hydrogen and fluorine, the hydrogen is oxidized whereas the fluorine is reduced.

$\sf H_{2} + F_{2} \longrightarrow 2HF$

The oxidation half reaction is:

$\sf H_{2} \longrightarrow {2H}^{ + } + {2e}^{ - }$

The reduction half reaction is:

$\sf F_{2} + {2e}^{ - } \longrightarrow {2F}^{ - }$

$\rule{100}{5}$
