Answers
Answer:
Galvanic Cells Electrolytic Cells
Spontaneous redox reactions convert the chemical energy to an electric energy Non-spontaneous redox reactions convert the electric energy to a chemical energy
Electric energy is generated by redox reactions Electric energy brings about the chemical reaction with the help of an external source
The cathode is the positive electrode and anode is the negative electrode The anode is the positive electrode and cathode is the negative electrode
The process of oxidation takes place at the anode and the reduction process occurs at the cathode Here, the oxidation process occurs at the cathode while the reduction process takes place at the anode
Half cells are set up in different containers and are connected through salt bridges Electrodes are kept in the same container in a molten or solution electrolyte
Application lies in Batteries Application lies in purifying copper and electroplating
