Question

The way, metals like sodium, magnesium and iron react with air and water is an indication of their relative positions in the ‘reactivity series’. Is this statement true ? Justify your answer with examples.​

Answer 1

Answer:

Yes, sodium reacts explosively even with cold water, it is most reactive. Magnesium reacts with hot water, it is less reactive than Na. Iron reacts only with steam which shows it is least reactive among the three.

Answer 2

Answer:

The statement is correct because they react with air and water at different rates and in different conditions. While sodium reacts spontaneously and violently with air and cold water, magnesium reacts with air less vigorously and with water when heated. Iron reacts with air very slowly and reacts with steam to form iron oxide and hydrogen being the least reactive among sodium, magnesium and iron.
