Meets AP® Chemistry experiment 21. This 3-experiment kit combines the Nernst equation, Faraday’s law, the ideal gas law, and Dalton’s law of partial pressures. Students determine which pair of 4 metals in metal salt solutions generates the most potential. This potential, taken at nonstandard conditions, is compared to the theoretical value calculated using the Nernst equation.

Students determine which pair of 4 metals in metal salt solutions generates the most potential. This potential, taken at nonstandard conditions, is compared to the theoretical value calculated using the Nernst equation. Students electrolyze water and compare the volume of gas evolved to the volume calculated from Faraday’s law.
Materials are sufficient for 30 students working in groups of 3.
