Question

Action on metals on acids. w/c metals can displace H from HCl? what metals can't? ?

Answer 1

see the elements' reactivity list.

Those metal which are above hydrogen in this series can replace hydrogen from HCl and others cant.

Li   K   Ba   Sr Ca   Na   Mg   Al  Mn  Zn  Cr   Fe  Cd  Co  Ni  Sn   Pb   *H  Sb  As  Bi   Cu    Ag  Pd  Hg  Pt    Au

Most Reactive ----------------------------------à  Least Reactive

Answer 2

Of common metals copper, silver and gold will not displace hydrogen from hydrochloric acid.

Answer 3

Most noble metals (Au, Ag, Pt) do not react to acid.
