What is Thermite Reaction Explain its Use and Give Equation

Answer: The ignition of Aluminium with Ferric oxide is called the thermite reaction. This is an exothermic process that releases heat along with its end products. Iron produced in this cycle is in liquid/molten state.

Fe₂O₃ (s) + Al (s) →Al₂O₃ + 2 Fe(l) + Intensity

Thermite reaction is utilized for the welding of rails (joining metals) called thermite welding.
