FAQs on Quick Revision: General Principles & Processes of Isolation of Elements - Inorganic Chemistry for NEET

1. What are the general principles of isolation of elements?
Ans. The general principles of isolation of elements include the use of suitable chemical reactions, physical processes like distillation and electrolysis, and the selection of appropriate reducing agents and solvents.
2. How is electrolysis used in the isolation of elements?
Ans. Electrolysis is used in the isolation of elements by passing an electric current through an electrolyte solution or molten compound. This process helps in the decomposition of the compound into its constituent elements.
3. What is meant by reducing agent in the isolation of elements?
Ans. A reducing agent is a substance that donates electrons to another substance during a chemical reaction. In the isolation of elements, reducing agents are used to remove oxygen or any other electronegative element from a compound to obtain the desired element.
4. What are the physical processes involved in the isolation of elements?
Ans. Physical processes like distillation, filtration, and sublimation are involved in the isolation of elements. These processes help in separating different components of a mixture based on their physical properties such as boiling point, solubility, or sublimation temperature.
5. How are suitable chemical reactions selected for the isolation of elements?
Ans. Suitable chemical reactions for the isolation of elements are selected based on the reactivity and availability of the elements. The reactions should allow the separation of the desired element from its compounds while minimizing the formation of unwanted by-products. Factors such as temperature, pressure, and catalysts are considered while selecting the chemical reactions.
