Electrochemistry: Galvanic Cells (Daniel Cells), Definition, Construction, Working and Cell Reactions
Question: What are Galvanic cells? Describe their construction, working and reactions.
Answer
The electrochemical cell which converts chemical energy from spontaneous redox reaction into electrical energy is called Galvanic cell or Daniel cell.
Construction: A galvanic cell consists of following parts.
1. A zinc rod dipped into a 1 M ZnSO4 solution
2. A copper rod dipped into a 1 M CuSO4 solution.
3.A salt bridge which consists of U shaped tube containing an innert electrolyte such as KCl.
4. A voltmeter to measure the current
