Question

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

Help me guys!!!!​

Answer 1

Explanation:

sulphuric acid is H2SO4 .

As Zinc is more reactive than hydrogen , it can displace it from its compound whereas copper is less reactive than hydrogen thus, cannot displace hydrogen from it's compound.

hope it helps..

Answer 2

Answer:

$\boxed{\pink{\textsf { Copper is less reactive than Hydrogen}}}$

Explanation:

Given that , zinc reacts with dilute Sulphuric Acid , to give Hydrogen gas , but copper doesn't . This is so because , when we look at the Reactivity Series , Zinc is placed above Hydrogen. So it replaces Hydrogen from the Sulphuric Acid .

✤ The reaction is :-

$\boxed{\red{\sf H_2SO_4 + Zn \to ZnSO_4 + H_2 }}$

• Zinc being more reactive than hydrogen displaces it from its salt solution .

Whereas , Copper is placed below Hydrogen in the reactivity series . So its unable to displace Hydrogen from Sulphuric Acid. Therefore Hydrogen gas is not released .

✤ The reaction is :-

$\boxed{\red{\sf H_2SO_4 + Cu \to \textsf{\textbf{ No Reaction }} }}$

• Copper being less reactive than hydrogen is unable to displace it from sulphuric acid .
