Question

why does zinc react with dilute sulphuric acid to give hydrogen gas but copper does not please give answers fast ​

Answer 1

Explanation:

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 H2O but copper cannot liberate H2 gas by reaction with dilute H2SO4.

Answer 2

Explanation:

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 H2O but copper cannot liberate H2 gas by reaction with dilute H2SO4.
