Why does zinc react with dilute sulphuri...

Why does zinc react with dilute sulphuric acid to give hydrogen gas but copper does not?

Text Solution

Verified by Experts

Zinc lies above hydrogen whereas copper lies below hydrogen in the electrochemical series. Hence, zinc is more reactive than `H^(+)` whereas copper is less reactive. Therefore, zinc reacts with dilute `H_(2)O` but copper cannot liberate `H_(2)` gas by reaction with dilute `H_(2)SO_(4)`.
