Galvanic Cell vs Electrolytic Cell Similarities and the Differences

1. Galvanic Cell Vs Electrolytic Cell:

Let’s compare the galvanic cell with the electrolytic cell in terms of similarities and differences.

Similarities b/w Galvanic Cell & Electrolytic Cell:

Both are electrochemical cells

Redox reaction takes place in both cells

Both cells contain Anode & Cathode

Oxidation takes place at Anode & reduction at Cathode.

 

Differences b/w Galvanic Cell & Electrolytic Cell:

 

    Galvanic cell 

        It changes chemical energy into Electrical energy.

1.Anode is –ve

2.Cathode is +ve

3.Spontaneous reaction occurs.

4.Does not require external voltage source.

 

Electrolytic cell 

It changes electrical energy into Chemical reaction.

1.Anode is +ve

2.Cathode is -ve

3.Non-Spontaneous reaction occurs.

4.Require external voltage source.
