A metal A, which is used in thermite process, when heated with oxygen gives an oxide B, which is amphoteric in nature? Identify A and B. Write down the reactions of oxide B with HC1 and NaOH.
Aluminium and Iron are used in a thermite process, however, only aluminium when heated with oxygen, gives aluminium oxide, which is an amphoteric substance, meaning it can react with both acids and bases. Hence, A is aluminium and B is aluminium oxide.
