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.
