Question

Explain the following :-
(a) corrosion and rancidity
(b) oxidation and reduction

Answer 1

Explanation:

a) Corrosion and rancidity are the process in which any metal gets corroded or rancid due to presence of oxygen, moisture, etc.

b) Oxidation is the process in which there is presence of oxygen and removal of hydrogen and Reduction is the process in which there is absence of oxygen and presence of hydrogen.

Answer 2

$\huge \bf \green{ \underline{answer}}$
$\bf \green {corrosion}$ : it is process in which metal are slowly eaten up by the action of air moisture or chemical.

$\bf \green{rancidity}$ : when the substance containing oil and fats are exposed to air they get oxide and become rancid due to which their smell taste and colour change this process is known as rancidity.

$\huge\green \bigstar$$\bf \green{oxidation}$ : the reaction in which oxygen is combined and hydrogen removed called oxidation.
$\bf \green{example }$ : C+O2-------> CO2

$\bf \green {reduction}$ : the reaction in which hydrogen combines and oxygen is removed called as reduction.
$\bf \green{example}$ : 2H2 + O2 -------> 2H2O.
