Electrochemical Cell
1. What is an Electrochemical Cell?
An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or using electrical energy to drive chemical reactions.
2. What are the types of Electrochemical Cells?
The two types of electrochemical cells are,
- Galvanic cells or voltaic cells
- Electrolytic cells
Galvanic cells are used to convert chemical energy into electrical energy whereas, electrolytic cells are used to convert electrical energy into chemical energy.
3. What is Standard Electrode Potential?
Standard electrode potential of an electrode is defined as the potential difference between the electrode and the electrolyte under standard conditions.
4. What are the Differences between Cathode and Anode?
The differences between the Cathode and Anode are :
Cathode |
Anode |
---|---|
Difference between Cathode and Anode |
|
Reduction occurs at Cathode. |
Oxidation occurs at Anode. |
(+) sign is used to show Cathode. |
(-) sign is used to show Anode. |
5. What is an Electrolytic Cell?
Electrolytic cell is a type of electrochemical cell that uses electric currents to speed up cell reactions. The chemical reaction occuring inside these cells is known as electrolysis. These cells can be used to electrolyze water into hydrogen and oxygen.
6. What is use of a Salt Bridge in an Electrochemical Cell?
Salt bridge is used to complete the circuit of an electrochemical cell, allowing current to flow across it. It also contributes to maintaining the cell’s overall electrical neutrality.
Electrochemical Cells
Electrochemical Cell is a device that may either generate electrical energy from chemical reactions or use electrical energy that is supplied to it to speed up chemical reactions. There are various types of electrochemical cells and they are used in our daily activities such as cells that are used in Watches, TV remotes, Clocks, etc.
In this article, we will learn about the basic concepts and topics of electrochemical cell, its representation, diagram, working principle, structure and notation. We will also explore the parts, types, and applications of electrochemical cell, along with its difference from electrolytic cell in detail.
