Question 1:

Which of the following statements is true about an electrochemical cell?

Explanation: An electrochemical cell converts chemical energy into electrical energy through redox reactions.

Question 2:

Which electrode in a galvanic cell is the site of oxidation?

Explanation: In a galvanic cell, the oxidation occurs at the anode, which is the electrode where electrons are lost.

Question 3:

What is the function of a salt bridge in an electrochemical cell?

Explanation: A salt bridge maintains electrical neutrality in the half-cells by allowing the flow of ions, balancing the charges, and preventing the solutions from mixing directly.

Question 4:

Which of the following represents the correct cell notation for the galvanic cell involving a copper electrode and a silver electrode?

Explanation: The cell notation for the galvanic cell involving a copper electrode and a silver electrode is B) Cu(s) | CuNO₃(aq) || AgNO₃(aq) | Ag(s).

Question 5:

Which of the following factors affects the cell potential of a galvanic cell?

Explanation: All of the factors mentioned in options A, B, and C affect the cell potential of a galvanic cell. Concentration, temperature, and electrode surface area can influence the rate of redox reactions and the movement of ions, thereby affecting the cell potential.
