Question

The components of water can be separated by
(1) Chemical method
(2) Physical method
(3) Both (1) and (2)
(4) None of these

Answer 1

The chemical which contains different elements in it and has a specific chemical formula then it is called a compound. Always the compound will be a pure of a chemical if it contains other impurities then it is going to be called as a mixture.

Complete step by step solution:
- In the question it is asked by using which way we can separate the components of water.
- Before going to know about the separation of the components of the water first we should know the chemical formula of water.
- The molecular formula or the chemical formula of water is ${{H}_{2}}O$ .
- Then water is an example for compounds because it contains a specific chemical formula and does not contain different elements in its throughout structure.
- Now to separate the components of the water physical methods are not sufficient because the hydrogen and the oxygen are bonded through a chemical bond.
- The chemical bonds (covalent bond) cannot be broken by physical methods like distillation and fractional distillation.
- But we can separate the components in water by using chemical methods like electrolysis etc.
Therefore the correct option is A.

Note: Water is a universal solvent and can be used for different purposes. By electrolysis we can separate the components present in water by the breaking of the chemical bonds between the hydrogen and the oxygen atom.
