Question

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

Answer 1

As we know that that Zinc is more reactive than hydrogen that's why it reacts with H2SO4 but copper is less reactive than hydrogen that's why it will not react with copper.

Answer 2

This is because zinc is placed higher than the hydrogen and is more reactive than hydrogen. Thus, it displaces it from hydrgen sulphate to form zinc sulphate and hydrogen is released. However copper is placed lower in the reactivity series and is less reactive than hydrogen. Therefore it does not react with sulphuric acid.
