When pH is 1, 2 3 4 5 or 6, it is considered an Acid. When pH is 8 9 10 11 12 13 or 14, it is considered a Base. 7 is the neutral point of acid and base. pH is calculated by the -log (H+)
Those are called bases. .....There are many different acids and bases that affect pH, but for clarity sake it will be easiest to think only in terms of hydrogen ions (H+) and hydroxide ions (OH-). When water has more free hydrogen ions floating around than hydroxide ions, it is acidic (pH less than 7).
