Explain the production of electricity in the simple voltaic cell.
- Magnesium is more electropositive than copper. Magnesium is the negative terminal.
- Each magnesium atom donates two electrons to form a magnesium ion. Mg --> Mg2+ + 2e-
- The flow of electrons from the magnesium ribbon to the copper through the external circuit results in the production of electricity.
- The hydrogen ions from the electrolyte(sodium chloride solution) are discharged at the copper plate by accepting electrons to form hydrogen gas. 2H+ + 2e- --> H2
What is the observation at each of the terminal?
