Name two metals that will displace hydrogen from dilute acids and two metals which will not.

Dear Student

Metals which lie above Hydrogen in the activity series ie. Zn, Al, Mg can displace hydrogen from dilute acids, because they are more reactive than H2. Metals which lie below hydrogen in the activity series i.e. Cu, Ag, Au cannot displace hydrogen from dilute acids, because they are less reactive than hydrogen.

Thanks
