Pictured above is the pH scale. It is used to determine if a substance is an acid or a base. Substances with a pH less than 7 are acidic. Substances with a pH over 7 are considered basic. Substances with a pH of 7 are neutral. Remember, it is possible for a substance to have a pH less than 1 or greater than 14.
