The ionization of water is the basis of the pH scale. Acidic solutions have a pH of 7 or less on the scale. Alkaline solutions have a pH of 7 or more o the scale. 7 is roughly equivalent to spring water. Human cells are a 7.
Organic compounds are molecules of one or more elements covalently bonded to carbon atoms.
One element is always hydrogen. Carbon bonds covalently . Each carbon atom can share electrons with up to 4 other atoms. These stable bonds link carbon atoms together in chains, to which hydrogen, oxygen, nitrogen, etc. attach. This carbon chain is the backbone from which other atoms can project to build 3-dimensional shapes.
