WebWhen pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one. And if A minus concentration over HA concentration is equal to one, that means that they have the same concentration. I forgot a minus sign there. This is a really helpful thing to ... 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.
