Question

define displacement reaction with the help of an example

Answer 1

Hello!



A displacement reaction is a reaction where one element gets displaced by another in the compound

NOTE: MORE REACTIVE ELEMENT DISPLACES LESS REACTIVE ELEMENT

Eg: When copper reacts with sulphuric acid it forms copper(II)sulphate with hydrogen

Cu+ H2SO4 --> CuSO4 + H2

But in displacement reaction iron will displace copper[it is more reactive than copper] to form Iron(II)sulphate and hydrogen

Fe + H2SO4 --> FeSO4 + H2



HOPE THIS HELPS U...☺
