Question

Give reasons for the following:-
Metals replace hydrogen from dilute acids whereas non- metals do not.

Answer 1

Answer:

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.
