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.
