Question
Iron can liberate H2 from dil. H2SO4 but copper cannot liberate H2 from dil. H2SO4.
Why?
Answer: Option A
:
A and C
Iron can liberate H2 from dil. H2SO4 but copper cannot liberate H2 from dil. H2SO4. This happens because Fe is more reactive than hydrogen. It can thus displace hydrogen from sulphuric acid and form iron sulphate. Whereas copper is less reactive than hydrogen so, it cannot displace hydrogen from sulphuric acid.
