Question

What is Thermit Reaction? Explain its use and give equation.

​

Answer 1

Answer:

The thermit reaction is the reaction of metal oxide with aluminium.The aluminium acts as a reducing element and the reaction is highly exothermic and hence called a thermite reaction.The aluminium reduces the oxide of another metal.Most of the it is Iron Oxide.The reaction can be shown as- Fe2o3+Al=Fe+Al2O3.

Hope this answer may you ☺️

Answer 2

Explanation:

A thermite reaction is basically iron oxide (rust) reacting with aluminum to produce molten iron. The products are aluminium oxide, elemental iron, and a large amount of heat. The reactants are commonly or thermite mixture is aluminum powder and iron oxide (rust) powder. When the mixture is heated, it starts reacting as the aluminum is more reactive than the iron and aluminium forms stronger and stable bonds with oxygen than iron.

Uses-

1.The reaction is used for thermite welding, often used to join rail tracks. 2.Thermites have extremely high temperature and also been used in metal refining, demolition of ammunitions, and in incendiary weapons.

3.Some thermite-like mixtures are used in fireworks.

4.A thermite reaction is used to purify the ores of some metals called as thermite process.
