WebMelting and boiling are state. changes. Energy has to be transferred to a substance in order to melt or boil it. This energy is needed to break the bonds between particles in the substance: WebWater can be separated into oxygen and hydrogen through a process called electrolysis. Electrolytic processes take place in an electrolyzer, which functions much like a fuel cell in reverse—instead of using the energy of a hydrogen molecule, like a fuel cell does, an electrolyzer creates hydrogen from water molecules.

The greater strength of ion-dipole attractions compared to hydrogen-bonding (dipole-dipole) attractions stabilizes the dissolved ion. Water is not the only electrolytic solvent, but it is by far the best.

WebThe most efficient electrolysis of hydrogen requires de-ionized (pure) water to make a KOH (potassium hydroxide) solution. The electrolysis process extracts hydrogen gas ( H 2 ) and oxygen gas ( O 2 ) from the water, and the KOH is recycled. Anode oxidation: 2H2O + 4KOH ==> O2 + 4H+ + 4OH– + 4K+ + 4e– ==> O2 + 4H2O + 4K+ + 4e– WebTo realize water purification copper, silver and electrolysis were applied. Disinfection has been applied for several decades. However, the mechanism has been known for only one hundred years. In 1680 Anthony van Leeuwenhoek developed the microscope. His discovery of microorganisms was considered a curiosity.
