The pH scale ranges from which values?

Explanation:
The pH scale is a log measure of hydrogen ion concentration in aqueous solutions, and at room temperature it spans from 0 to 14. This range corresponds to [H+] from 1 M (pH 0) to 1×10^−14 M (pH 14), with neutral water at pH 7. So, the standard range used for most teaching and everyday use is 0 to 14. Values outside this range can occur in very concentrated solutions or under nonstandard conditions, but they aren’t part of the typical scale. The other ranges don’t fit because they either limit the scale to acidic or neutral only (0 to 7), omit the strongest acids (1 to 14), or imply negative pH values (−14 to 14), which aren’t part of the standard scale.
