7-14 is the range of base in a pH scale
Anything from above 7 to 14 is a base on the pH scale
pH 14 is the strongest base and it is usually sodium hydroxide
pH depends on concentration. Strong bases are for example: NaOH KOH Ca(OH)2 http://en.wikipedia.org/wiki/Base_(chemistry)
pH is measured on a 0-14 scale. When something has a pH of 0-7 it is considered an acid. When it is from 7-14 it is a base. Therefore, something falling within the range of 4.5-5.2 is a weak acid and not a base.
Bases run from 7.1 to 14 on the ph scale. A strong base would be in the 12-14 range. A 3ph is a relatively strong acid.

pH ranges from 1 (acid) to 14 (base). As far as acceptble range, you need to make clearer what else you need to know...like pH range of blood.

pH range of indicator should be in the rapid pH gradient.

It depends on the concentration of the base added. If very dilute, the pH will be slightly greater than 7 and if quite concentrated, the pH can be as high as 14. Note: If the solution is acidic, the pH will be less than 7. (Pure water has pH = 7)
you learnt in school so why do you need answers from the websit
The conjugate base of a weak acid in the buffer system resists a drop in pH. This base can react with any added hydrogen ions to maintain the pH within a relatively constant range.
Technically, the pH range is 0 to 14. 0 to 7 is acidic, 7 is neutral, and 7 to 14 is basic. However, in very rare situations, an acid can have a pH of -1 and a base can have a pH of 15. But I doubt you need to know that.
A normal pH range for blood is around 7.35 to 7.45. Any pH value outside of this range can indicate an imbalance in the body's acid-base status which may be a sign of an underlying health issue.
