A student wishes to determine the chloride ion concentration in a water sample at 25 °C using a galvanic cell constructed with a graphite electrode and a half-cell of AgCl(s) + e⁻ → Ag(s) + Cl⁻(aq) E°red = 0.2223 V And a copper electrode with 0.500 M Cu²⁺ as the second half cell Cu²⁺(aq) + 2 e⁻ → Cu(s) E°red= 0.337 V The measured cell potential when the water sample was placed into the silver side of the cell was 0.0657 V.
What is the standard potential of the cell?
What is the value of standard free energy (in kJ) for this reaction?
What is the balanced equation for the overall reaction in acidic solution?
The measured cell potential is 0.0657, what is the concentration of chloride ions in the solution?
