Alkalis have a pH in which range?

Explanation:
Alkalis are basic substances that raise the pH of a solution. On the pH scale, 0 is most acidic, 7 is neutral, and 14 is most basic. Because alkalis dissolve in water to form hydroxide ions, their solutions sit on the high end of the scale, typically from about 8 up to 14. So the range 8-14 is the one that describes alkalis. The other ranges represent acidic or neutral solutions: 3-4 and 0-2 are acidic, and 5-7 is neutral to mildly acidic, so they do not describe alkalis.
