For a voltaic cell involving lead and gold, the anode and cathode are identified, with half-cell reactions provided. The overall reaction and standard cell notation are presented, along with details on electron flow and cation movement.
Half-cell reactions:
Anode: Pb(s) - 2e⁻ → Pb²⁺(aq)
Cathode: Au³⁺(aq) + 3e⁻ → Au(s)
Overall reaction:
Pb(s) + 2Au³⁺(aq) → Pb²⁺(aq) + 2Au(s)
Standard cell notation: Pb(s) | Pb²⁺(aq) || Au³⁺(aq) | Au(s)
Direction of electron flow: From anode to cathode on the wire
Cations in salt bridge: Cations move towards the cathode
Cell potential calculation: Use standard reduction potentials to calculate cell potential
