Sample Questions on Electrode Potential

Question 1:  What processes are involved in redox reactions?

Answer:

A redox process is an electron transfer reaction that involves both reduction and oxidation, with reduction being the intake of electrons and oxidation being the release of electrons.

Question 2: How does a redox reaction produce electricity?

Answer:

A galvanic cell, also known as a Voltaic cell, is an electrochemical cell that generates electrical energy through a redox reaction or redox process. A voltaic cell is made up of two half-cells that perform either the reduction or oxidation processes.

Question 3: How Electrolysis is an example of a redox reaction?

Answer:

Electrolysis is a redox reaction because reduction occurs at the cathode and oxidation occurs at the anode, and both of these reactions occur at the same time.

Question 4: What does the reduction process do?

Answer:

Chemical entities lose electrons during the reduction process, lowering their oxidation number. The oxidation part of the reaction involves the loss of electrons. Reduction is the polar opposite of oxidation.

Cu²⁺+2e^– → Cu(s)

Question 5: What is a redox couple example?

Answer:

In redox reactions, a redox pair is formed by the oxidised and reduced versions of each reactant. Redox couples are denoted as “Ox/red.” For example- Cu²⁺/Cu and Zn²⁺/Zn, have an oxidised version on the left and a reduced version on the right, separated by a slash.

Question 6: What are the uses of electrode potential?

Answer:

• It helps with corrosion and pitting investigations, as well as reaction control.
• Electrode Potential can be used to help choose materials and equipment for reaction control.
• Corrosion caused by electrochemical and chemical reactions and processes can be predicted with the help of this programme.

Electrode Potential and Standard Electrode Potential are key concepts in the field of electrochemistry which is the branch of chemistry that deals with relationships between electric potential differences and observable chemical change. Electrode Potential is also used extensively in the development of sustainable battery technologies, as all modern-day batteries work on this principle to create voltage for the smooth operations of electronic gadgets. This article deals with the topic of Electrode Potential and Standard Electrode Potential in detail and helps us understand how electricity or potential is produced using chemistry.
