What is the pH scale range for acids and bases?

Answer 1

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)

Answer 2

pH scale is values from 1 to 14, in which values above 7 are values for bases. pH is calculated from following formula: pH = -log(10) [H+], where [H+] is concentration of protons in solution.

A base has a pH greater than 7.

Answer 3

Acids are below 7, bases are above 7.

The range for pH is usually given as 0-14, though with exceptionally strong acids or bases in concentrated solutions it's possible to exceed that slightly.

Answer 4

The pH scale ranges from '0' to '14'

'0' to '6' is acidic

'7' is neutral

'8' to '14' is alkaline

Answer 5

The pH scale ranges from 0 to 14. Acids have a pH below 7, with lower values indicating stronger acidity. Bases have a pH above 7, with higher values indicating greater basicity.

Answer 6

Generally, 7.0 (Neutral)-13.0 is considered alkaline, or basic.

Answer 7

The pH range for a basic substance is 6.9 - 14+.

Answer 8

Bases are substances that have a pH higher than 7. In aqueous systems, the pH very rarely gets above 14, however higher pH values are possible.

Answer 9

Basic solutions have a pH over 7.

Answer 10

11-14
