of hydrogen – and converting it back to electrical energy in fuel cells – is one of the technologies already in place but not yet completely developed for large-scale operation.
Information and ideas:
• Students must wear safety goggles. Point out that students must immediately rinse their eyes or skin if sodium carbonate or soda solutions splashes on them.
• Working with a flame can result in burns or fires. Before a lighter is used the first time, check to ensure that it is working properly and adjust the flame height.
• This experiment takes time for additional preparations, as you may need to first set up the electrolytic cells. In the Additional information section you will find instructions on how to set up an electrolytic cell.
