Question

The lower the position of the metallic element in the electrochemical series the greater is its tendency to to be liberated at cathode. How? ​

Answer 1

the element which is present at lower in electrochemical series will have more reducing power

hence it will itself get oxidised by reducing the other element

since u know oxidation takes place at cathode hence the element which is present at lower in electrochemical series will have grater tendancy to be liberated at cathode

hope it helps

${\huge {\mathfrak {Answer :}}}$

As the elements which are at lower position (in electrochemical series) will more like to be more metallic (since they are at lower position ) ..

And as we know that metals are electropositive thus they will attract towards cathode (since positive chargetends to move towards negative charge )
