Question

Differentiate between iron and copper in terms of their reactivity towards dilute hydrochloric
acid. Write the chemical equations for the reactions.

Answer 1

Answer:

I hope it will helpful to you

Answer 2

Answer:

Okay, heres your answer:

According to the reactivity series, iron(Fe) is a more reactive metal than copper(Cu). Also, hydrogen(H) is more reactive than copper and iron is more reactive than hydrogen (according to the reactivity series)

Cu ∠ H ∠ Fe

Now, lets look at each of the reactions.

we know that , acid + metal = salt + hydrogen

we also know that iron is more reactive than hydrogen.

hence iron will displace hydrogen in HCL and form FeCl3 and liberate Hydrogen.

Fe + HCl ⇒ FeCl3 + H2

Now lets look at copper

we know that copper is less reactive than Hydrogen. Hence no reaction will occur because copper being the less reactive metal can't displace hydrogen in HCL.

Have a great day!
