उत्तर
- Copper has a positive reduction potential. Elemental copper is more stable than Cu2+.
- Copper having a positive sign for electrode potential merely means that copper can undergo reduction at a faster rate than the reduction of hydrogen.
- The electron-giving reaction (oxidation) of copper is slower than that of hydrogen. It is determined from the result of the S.H.E (Standard Hydrogen Electrode) potential value experiment.
