Cell, Electrochemical Cell, Diagram, and Structure
What is Cells?
The device which convert electrical energy into chemical energy or chemical energy into electrical energy is called cell.
Types of Cells
Cells are of two types;
1. Electrochemical Cell
The cell which convert chemical energy into electrical energy is called electrochemical cell.
Eg: Daniell cell
Daniell Electrochemical Cell Diagram
2. Electrolytic Cell
The cell which convert electrical energy into chemical energy is called electrolytic cell.
Ex- electrolysis of NaCl.
o In electrolytic cell redox reaction takes place.
o In electrolytic cell non-spontaneous (ΔG = positive) reaction type is proceed.
o For this cell, the value ΔG is positive.
The Electrolysis of Molten NaCl
If H Cl solution is take place in electrolytic cell then the following reaction takes place at cathode and at anode
H CL ⇔ H+ Cl–
At cathode: H+ + e- → ½ H2(g)
At anode: Cl– → ½ Cl2(g) + e-
