In an electrochemical cell, the electrode having a lower reduction potential will act as:a)Salt bridgeb)Electrolytec)Anoded)CathodeCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

A substance with lower reduction potential has more tendency to oxidize .in a electrochemical cell anode performs oxidation reaction hence the electrode will function as a anode

Answer

If it has low reductional potential it will perform oxidation i.e at anode

Answer

Introduction:
An electrochemical cell is a device that converts chemical energy into electrical energy through redox (reduction-oxidation) reactions. It consists of two electrodes, an electrolyte, and a salt bridge. The electrode with a lower reduction potential will act as the anode in the cell.

Explanation:
- Electrode: An electrode is a conductor through which electric current enters or leaves a medium. In an electrochemical cell, there are two electrodes: the anode and the cathode.
- Reduction Potential: The reduction potential of an electrode is the tendency of the species at the electrode to gain electrons and undergo reduction. It is a measure of the electrode's ability to attract electrons.
- Anode: The anode is the electrode where oxidation occurs. It loses electrons and is negatively charged.
- Cathode: The cathode is the electrode where reduction occurs. It gains electrons and is positively charged.

Lower Reduction Potential:
The electrode with a lower reduction potential will act as the anode in an electrochemical cell. This is because the species at the electrode with the lower reduction potential has a higher tendency to lose electrons and undergo oxidation.

Reasoning:
- In a redox reaction, oxidation occurs at the anode and reduction occurs at the cathode.
- The electrode with a higher reduction potential will attract electrons more strongly and undergo reduction.
- The electrode with a lower reduction potential will have a weaker tendency to attract electrons and will undergo oxidation.
- Therefore, the electrode with a lower reduction potential acts as the anode, where oxidation occurs.
- The anode supplies electrons to the external circuit, allowing the flow of current.

Conclusion:
In summary, the electrode with a lower reduction potential acts as the anode in an electrochemical cell. It undergoes oxidation and supplies electrons to the external circuit, while the electrode with a higher reduction potential acts as the cathode, where reduction occurs. Understanding the roles of the anode and cathode is crucial in understanding the functioning of electrochemical cells and their applications in various fields.

Answer

The electrode having lower reduction potential will have lesser tendency to gain electrons.
i.e. act as anode.
