Question

Give reason why do metals displace hydrogen and from acid but non metals do not? ​

Answer 1

Answer:

Hydrogen from dilute acids can only be replaced if electrons are supplied to H+ ions of the acid.Metals have a tendency to lose electrons and hence they supply electrons i.e. they are electrondonors. That is why metals displace hydrogen from dilute acids. On the other hand non-metal is an electron acceptor. It cannot supply electrons to H+ and hence it does not displace hydrogen from dilute acids.
