FAQs on JEE Main 2025-26 Redox Reactions and Electro Mock Test: Practice & Solutions
1. What is a redox reaction?
A redox reaction is a chemical reaction in which there is a simultaneous reduction (gain of electrons) and oxidation (loss of electrons) of reactants. It involves the transfer of electrons between two species, making it central to many biological and industrial processes.
2. How do you identify oxidation and reduction in a reaction?
To identify oxidation and reduction:
• Oxidation: Loss of electrons or increase in oxidation number.
• Reduction: Gain of electrons or decrease in oxidation number.
Check which elements gain or lose electrons to determine the process.
3. What is the significance of the electrochemical series?
The electrochemical series is a list of elements arranged according to their standard reduction potentials. It helps predict the direction of redox reactions, the feasibility of a reaction, and relative strengths as oxidizing or reducing agents.
4. Differentiate between electrolytic cell and galvanic cell.
A galvanic cell generates electrical energy from spontaneous redox reactions, while an electrolytic cell uses electrical energy to drive non-spontaneous reactions. In a galvanic cell, anode is negative and cathode is positive; in an electrolytic cell, anode is positive and cathode is negative.
5. What are oxidizing and reducing agents? Give examples.
An oxidizing agent gains electrons and is reduced itself (e.g., KMnO4, Cl2). A reducing agent loses electrons and is oxidized itself (e.g., Zn, H2).
6. What is electrode potential?
The electrode potential is the measure of the tendency of an electrode to lose or gain electrons when it is in contact with its own ions in solution. It is expressed in volts (V) and measured under standard conditions as standard electrode potential (E°).
7. Explain oxidation number and its importance.
The oxidation number is the hypothetical charge an atom would have if electrons were allocated according to certain rules. It helps identify oxidized and reduced species in a reaction and is crucial for balancing redox equations.
8. What is a disproportionation reaction? Give an example.
A disproportionation reaction involves a single substance acting as both oxidant and reductant, undergoing simultaneous oxidation and reduction. For example, in 2H2O2 → 2H2O + O2, hydrogen peroxide is both oxidized and reduced.
9. How do you balance redox reactions using the ion-electron method?
Balancing redox reactions by the ion-electron method involves:
- Writing separate half-reactions for oxidation and reduction,
- Balancing atoms (except H and O),
- Balancing O using H2O and H using H+,
- Adding electrons to balance charges,
- Equalizing electrons and combining half-reactions.
10. What is the function of a salt bridge in an electrochemical cell?
A salt bridge completes the circuit in an electrochemical cell, maintaining electrical neutrality by allowing the flow of ions between the half-cells. It prevents charge buildup and enables continuous current flow.
11. What are some important applications of redox reactions in daily life?
Key applications of redox reactions include:
- Batteries and fuel cells for power
- Corrosion and rusting of metals
- Photosynthesis and respiration
- Industrial processes like bleaching, electroplating, and water purification
12. How is the emf of a cell calculated from standard electrode potentials?
The emf (Ecell) of a cell is calculated using the formula: Ecell = E°cathode – E°anode. Use the standard reduction potentials of the cathode and anode to find the cell's overall voltage under standard conditions.
