To determine which of the options could represent the pH of a strong base, we should first recall what pH and pOH represent and the relationship between
-
pH Scale: Ranges from 0 to 14. A pH less than 7 indicates an acid, a pH of 7 indicates neutrality, and a pH greater than 7 indicates a base.
-
Relationship:
and are related through the ion product of water ( ): From this, if you know , you can find and vice versa.
Now, let's evaluate each option:
a.
b.
c.
d.
Thus, the options that could represent the pH of a strong base are:
- b.
(pH = 12) - d.
(pH = 12)
Both b and d represent the pH of a strong base.
