Question

Why does zinc react with dilute h2so4 to give hydrogen gas but copper does not?

Answer 1

Explanation:

#Answer#

Note that Copper is a metal which is placed below Hydrogen in the Metallic Reactivity series, hence, it does not react with any dilute acid to give Hydrogen gas. On the other hand, Zinc is a quite active metal, and is placed above Hydrogen in the Activity series, so it reacts with dilute acids to form Hydrogen gas.

hope this helps☺✌❤

Answer 2

Zinc reacts with dilute H2SO4 to give hydrogen gas but copper does not , It is due to the fact that copper is less reactive than Hydrogen, So copper is unable to displace Hydrogen from its dilute solution.
