What is the difference between Bases and Acids?
Acids are H+ donors and Bases are H+ acceptors in chemical processes. Example: HCl gives H+ in the solvent water to become H+ and Cl- and is an acid. This is only one of several definitions of acids and bases but in my opinion the easiest to understand. Also, acids have a pH below 7 and bases have a pH above 7. The pH means the molar concentration of [H+] ions, 1 pH meaning 1 * 10 ^ -1 moles of [H+] ions per liter and 2 pH meaning 1 * 10 ^ -2 moles per liter. So, each 1 decrease on the pH scale means 10 times more [H+] ions and each 1 increase means 10 times less [H+] ions.
