Study Notes

Electrochemistry

Electrochemistry is the study of the relationship between chemical reactions and electricity.

Electrochemical Cells

The purpose of electrochemical cells is to convert chemical energy into electrical energy or vice versa.
Electrochemical cells are classified into two types: galvanic cells and electrolytic cells.

Galvanic Cells and Electrolytic Cells

The main difference between galvanic cells and electrolytic cells is the direction of energy flow: galvanic cells convert chemical energy into electrical energy, while electrolytic cells convert electrical energy into chemical energy.
In a galvanic cell, chemical energy is transformed into electrical energy.
In an electrolytic cell, non-spontaneous processes can be forced to occur by providing external energy in the form of electrical energy.
