Copper does not react with dilute sulphuric acid

Answers

Answered by sayanakashyap

no copper also react with dilute sulphuric and hydrogen gas will formed

SidGr8: Copper does not react with dilute sulphuric acid as its reduction potential is higher than that of hydrogen. Copper does not displace hydrogen from non-oxidising acids like HCl or dilute H2SO4.

But, concentrated sulphuric acid is an oxidising agent. So, when copper is heated with conc.H2SO4, a redox reaction occurs and the acid gets reduced to sulphur dioxide.

SidGr8: CuO(s) + H2SO4(aq) → CuSO4(aq) + H2O(l)

SidGr8: hopefully this anwers your doubt

Prasanna15678: There cannot be any reaction because

Prasanna15678: If you observe the reactivity series, copper is below Hydrogen

Prasanna15678: so copper cannot displace hydrogen from H2SO4

SidGr8: correct but there will be a reaction

Prasanna15678: what's the reaction?
