pH Scale: Acids, bases, pH and buffers (article) | Khan Academy
The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.

Acid-Base Concentration. - Khan Academy Help Center
Dec 22, 2016 · With acids (which have pH's less than 7), the pH will increase to be closer to 7. If the water is acidic, pH will go down to make the solution more acidic, and if it is basic, the pH will go up to make the solution more basic.
