1.	Consider the Fig. 3.2 and answer the following questions.
Answer» (i) Cell ‘B’ will act as electrolytic cell as it has lower emf ∴ The electrode reactions will be: Zn²⁺ + 2e^– ⎯→ Zn at cathode Cu → Cu²⁺ + 2e^–at anode (ii) Now cell ‘B’ acts as galvanic cell as it has higher emf and will push electrons into cell ‘A’. The electrode reaction will be: At anode : Zn → Zn²⁺ + 2e^– At cathode : Cu2+ + 2e– ⎯→ Cu

Answer»

(i) Cell ‘B’ will act as electrolytic cell as it has lower emf

∴ The electrode reactions will be:

Zn²⁺ + 2e^– ⎯→ Zn at cathode

Cu → Cu²⁺ + 2e^–at anode

(ii) Now cell ‘B’ acts as galvanic cell as it has higher emf and will push electrons into cell ‘A’.

The electrode reaction will be:

At anode : Zn → Zn²⁺ + 2e^–

At cathode : Cu2+ + 2e– ⎯→ Cu
