Question

Explain why silver does not evolve hydrogen in reacting with dilute sulphuric acid.

Answer 1

Silver is less reactive than hydrogen and so placed below hydrogen in the reactivity series. Metals which are less reactive than hydrogen cannot displace hydrogen from acids. This is why silver does not displace H2 when it reacts with dil H2SO4. So, when silver metal is added to dilute H2SO4, no reaction takes place. 

Ag + H2SO4 → no reaction

Answer 2

sliver is less reactive than hydrogen & so placed in the reactivity series . metals  which are less reactive than hydrogen cannot displace hydrogen from acids  .  this is why sliver does not displace H2  when it reacts with dil H2SO4 so ,when sliver metal is added to dil H2SO4 , no reaction take place .                        Ag  + H2So4   = no reaction .
