1. In an electrochemical cell, oxidation occurs at the:
Cathode
Anode
Salt bridge
External circuit
2. Which type of electrochemical cell uses an external power source to drive a non-spontaneous reaction?
Galvanic cell
Voltaic cell
Electrolytic cell
Fuel cell
1. In an electrolytic cell, the cathode is positively charged.
True
False
2. A salt bridge is used to maintain electrical neutrality in a galvanic cell.
True
False
1. The process of gaining electrons is called .
2. In a galvanic cell, chemical energy is converted into energy.
1. Differentiate between a galvanic cell and an electrolytic cell in terms of spontaneity of reaction and energy conversion.
2. Consider a voltaic cell based on the reaction: Zn(s) + Cu²⁺(aq) → Zn²⁺(aq) + Cu(s). Given E°(Zn²⁺/Zn) = -0.76 V and E°(Cu²⁺/Cu) = +0.34 V. Calculate the standard cell potential (E°cell) for this reaction.
Match each term on the left with its definition on the right.
1. Anode
a. Site of reduction
2. Cathode
b. Site of oxidation
3. Redox reaction
c. Reaction involving electron transfer
