Question

the process that does not involve in oxidation

Answer 1

The processes are:

1. Corrosion- Metal reacts with atmospheric water vapour and corrode their surface.

2. Neutralisation- Acid and base reacts to form salt and water.

3. Preparation of ammonia by habers process.

4. Metallurgic processes

Answer 2

The process that does not involve in oxidation, formation of Fe(Co)_5 from Fe.

Explanation:

• Oxidation takes place when an atom, molecule, or ion drop one or many electrons in a chemical response.
• When oxidation takes place, the oxidation state of the chemical species rises.
• Oxidation doesn't necessarily involve oxygen, Originally, the term was used when oxygen caused electron loss in a reaction.

During the transformation,

                                        $Fe +5 CO \rightarrow Fe(CO)_5$

The oxidation number of iron metal is 0.

The oxidation number of iron in $Fe(CO)_5$ is also 0 as CO is a neutral which having 0 oxidation number.

There is no change in the oxidation number of iron, Iron is not oxidized.

To know more:

The process which does not involve oxidation is respiration and rancidity and rusting of iron and slaking of lime choose one
