Question

what are the importance of decomposition reaction in Metal Industries give answer with three points

Answer 1

ANSWER---

◆ The reaction in which single substance decomposes two or more substances is called 'DECOMPOSITION REACTION'.

◆ There are three type of decomposition
1. Thermal Decomposition
2. Electrolytic Decomposition
3. Sunlight Decomposition

● When the decomposition reaction carried by heat is called thermal decomposition.

Example = 2FeSO4 --heat--- Fe2O3 + SO2 + SO3

● When the decomposition reaction carried by electric current is called electrolytic decomposition.

Example = H2 --electric current-- 2H + O2

● When the decomposition reaction carried by sunlight is called sunlight decomposition.

Example 2AgCl --sunlight-- 2Ag + Cl2

◆ importance of decomposition reaction in Metal Industries

● Electrolytic is used in the extraction of metal from their naturally occurring compounds, generally chloride and Oxides.

● Thermal decomposition is used for the production of CaO (Calcium Oxide). from carbonate which is a major constitute of cement.

● Molten NaCl is electrolytically decomposed to form sodium metal.

● Aluminium metal is obtained by electric decomposition of bauxite ore mixed with cryolite.

Answer 2

Explanation:

importance of decomposition reaction in metal industries:

1. Electrolytic decomposition is used for extraction of metals from their naturally occurring compounds,generally oxides and chlorides.
2. molten NaCl is electrolytically decomposed to form the sodium metal.
3. aluminum metal is obtained by the electric decomposition of bauxite mixed with cryolite.
