Vedclass · Answer

(C) Metals that are more reactive than hydrogen (i.e.,have a negative standard reduction potential) can displace hydrogen from dilute acids.$Fe$ and $Al$ are both more reactive than hydrogen.However,in the context of standard textbook questions where a single choice is required,$Al$ is a classic example of a metal that reacts with dilute $H_2SO_4$ to liberate $H_2$ gas.Reaction: $2Al(s) + 3H_2SO_4(dil) 	o Al_2(SO_4)_3(aq) + 3H_2(g) \uparrow$.
