Most chemical reactions and virtually all biological processes take place not between pure solids, liquids or gases, but rather among ions and molecules dissolved in water or other solvents (i.e. in solution). In this module we will therefore examine the various types of solutions and their properti ...

Electrolysis of water
Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water.This technique can be used to make hydrogen fuel (hydrogen gas) and breathable oxygen; though currently most industrial methods make hydrogen fuel from natural gas instead.
