Question

Name two metals which diaplace hydrogen from strong caustic alkalises.write the chemical equations in support of your answer

Answer 1

 Iron and aluminium will displace hydrogen from dilute acids as they more reactive then hydrogen. Mercury and copper cannot displace hydrogen from dilute acids as they are less reactive than hydrogen. hope it helps u

Answer 2

Answer:

1.Zinc

Zn(s)+2KOH(aq)------>K2ZnO2(aq)+H2(g)

2.Lead

Pb(s)+2NaOH(aq)-------->Na2PbO2(aq)+H2(g)

HOPE THIS IS THE RIGHT ONE
