The pH scale ranges from how many to how many?

Explanation:
The pH scale measures how acidic or basic a solution is, using pH = -log10[H+]. A higher hydrogen ion concentration means a lower pH, so acids have pH below 7, bases above 7, and neutral is 7. Under standard conditions (about 25°C), the scale commonly used ranges from 0 to 14, with 0 being very acidic and 14 very basic. The boundaries come from the typical water autoionization and the workable concentration ranges for common solutions. So the pH scale ranges from 0 to 14.
