WebA solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. Weak acid/base. Weak acids/bases only partially dissociate in water. Finding the pH of a weak acid is a bit more complicated. WebAnswer (1 of 3): Here is the answer.
