Question

List four metals that will mot replace hydrogen in an acid

Answer 1

The four metals that will not replace hydrogen in an acid are Cu, Ag, Au, Hg.

Explanation:

• As Copper Cu lies below the hydrogen, this is why it is less reactive and ca not replace Hydrogen from its compound.

• Silver Ag also lies below the hydrogen and therefore it is less reactive to displace Hydrogen.

• Gold Au becomes less reactive than Hydrogen due to its placement below Hydrogen acid.

• Mercury Hg is less reactive than Hydrogen
