What does splitting hydrogen gas and chlorine from H2O or water have to do with science?

Answer 1

Chlorine is added to water as a disinfectant, and most of it will evaporate if the water is allowed to sit for a period of time, perhaps heating it a little. It is toxic to fish and city water should be declorinated or let stand before being put in an aquarium.

Electrolysis is a process of splitting Hydrogen gas and Oxygen.

Electrolysis is certainly and old experiment, and easy to replicate.
However, electrolysis (and similar methods) are also part of current research.

• Where do you think the Space Shuttle gets its fuel?
• Oxygen on the International Space Station is stored as water (which is mostly oxygen by weight) and the easiest/safest way to transport and store the oxygen. Electrolysis is used to separate the oxygen from the water to make breathable air
• Fuel Cell Technology requires a light fuel as input (hydrogen, methane, etc), and essentially does reverse electrolysis to make electricity.
• There are proposals of converting electricity into hydrogen to be used in automobile fuel
• You can buy jewelery welders that use electrolysis
• You will find some very controversial literature on HHO as fuel for automobiles, as well as using it as a fuel supplement (which is essentially just water that has been split with electrolysis).
• Some people are coupling electrolysis with solar/wind electricity generation for storage of energy for winter heating or use as stove fuel.

Anyway, electrolysis is an interesting setup for chemistry and experimental design, and may help with the understanding of the relationship between Hydrogen, Oxygen, and Water.

But, it is also part of multi-branched research on energy, energy storage, and energy usage.

Answer 2

Splitting hydrogen gas and chlorine from water involves a process called electrolysis, which is a scientific method of using electricity to break apart compounds into their individual elements. This experiment demonstrates the principles of chemical reactions, conductivity, and the reactivity of different elements. It also highlights the importance of water as a source of hydrogen fuel and the potential applications of electrolysis in producing clean energy.
