Solution

The correct option is B Ferric oxide and aluminium powder
$\begin{matrix} Ferric oxide and aluminium powder (F e_{2} O_{3} + A l) 2 A l + F e_{2} O_{3} \to A l_{2} O_{3} + 2 F e It is used for Thermite welding. Hence option B is correct. \end{matrix}$

Q. Assertion :In thermite welding, aluminium powder and

F e_{2} O_{3}

are used. Reason: Aluminium powder is a strong reducing agent.

${F e}_{2} O_{3}$ + $A l$ $\to$ $F e$ + ${A l}_{2} O_{3}$
This is the reaction used in thermite welding process. Calcium can also be used instead of aluminium in this process.

Q. Assertion :Statement- I : Thermite mixture

{F e}_{2} O_{3}

+ Al (powder) is used in the welding. Reason: Statement- II : Al is a good reductant

${F e}_{2} O_{3}$ + $A l$ $\to$ $F e$ + ${A l}_{2} O_{3}$ + $h e a t$
This is the reaction used in thermite welding process. Calcium can also be used instead of aluminium in this process.

Q. Assertion :Aluminium is use in thermite process. Reason: Aluminium has a high affinity for oxygen. It readily removes oxygen from oxides of less reactive metals so it is used in thermite welding.
