Question

name one metals which can displace hydrogen from dilute acid and on metals which cannot do so​

Answer 1

Answer:

metals which displace hydrogen are: Li, K, Ca, Na,Mg,Al, Zn, Cr, Fe, Ni, Sn, Pb.

Metals which do not displace hydrogen are: Cu, Ag, Au, Hg, Pt, Cl, F, Br, I

Explanation:

metals which are placed before hydrogen in theactivity series displace hydrogen from dilute solution. they are: Li, K, Ca, Na,Mg,Al, Zn, Cr, Fe, Ni, Sn, Pb.

Metals which are placed below hydrogen in the activity series do not displace hydrogen. They are:Cu, Ag, Au, Hg, Pt, Cl, F, Br, I

Answer 2

: Required Answer

$\longrightarrow$ Zinc (Zn) and Magnesium (Mg) are the two metals which will displace Hydrogen from dilute acids as they are very reactive metals. Gold (Au) and Silver (Ag) are the metals which will not replace Hydrogen from dilute acids as these metals are less reactive.
