Question 1

Write the overall cell reaction for the galvanic cell given below.

Pt(s) ∣ H2(g) ∣ H+(aq) ∣∣ Cl2(g) ∣ Cl-(aq) ∣ Pt(s)


◦ 2 H+(aq) + 2 Cl2(g) → 2 HCl(aq)
◦ Pt(s) + H2(g) + Cl-(aq) → Pt(s) + 2 H+(aq) + 2 Cl2(g)
◦ H2(g) + Cl2(g) → 2 H+(aq) + 2 Cl-(aq)
◦ No reaction would occur because there is no salt bridge.

Question 2

In a galvanic cell constructed from Pb(s) | Pb+2(aq) || Hg+1 | Hg(s), which of the electrodes will gain mass?
◦ the cathode, Hg (s)
◦ the anode, Pb (s)
◦ the cathode, Pb (s)
◦ the anode, Hg (s)
