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+)
This results in a relatively low pH compared to strong bases. Bases range from a pH of greater than 7 (7 is neutral, like pure water) to 14 (though some bases are greater than 14).
