Question

define oxidation and reducation reaction in terms of loss or gain in hydrogen please help me I will put it in brain liest ​

Answer 1

Reduction is the loss of oxygen atom from a molecule or the gaining of one or more electrons. A reduction reaction is seen from the point of view of the molecule being reduced, as when one molecule gets reduced another gets oxidised.

$\huge \bf\red{\mid {\overline {\underline {Answer}}} \mid}$

$\underline {\Huge \bold {Oxidation:}}$

If a chemical substance gains oxygen or loses hydrogen, it is called oxidation. Oxidation is also defined as addition of oxygen to an element or compound and the removal of hydrogen from a compound. There is a loss of electrons.

For example,

☯ 2Mg + O2 => 2MgO [Addition of Oxygen]

☯ 2Hcl => Cl2 [Removal of Hydrogen]

$\underline {\Huge \bold {Reduction:}}$

If a chemical substance gains hydrogen or loses oxygen, it is called reduction. Reduction is also defined as addition of hydrogen to an element or a compound and the removal of oxygen from a compound. There is a gain of electrons.

For example,

☯ 2H2 + O2 =>2H2O [Addition of Hydrogen]

☯ CuO + H2 => Cu + H2 [Removal of oxygen]
