Problem: The following scene represents three weak acid HA (where A = X, Y, or Z) dissolved in water (H2O is not shown):(e) If equimolar amounts of the sodium salts of the acids (NaX, NaY, and NaZ) were dissolved in water, which solution would have the highest pOH? The lowest pH?

FREE Expert Solution

The least acidic (based on the number of H3O+) is HX. 

Recall:
pH=-log[H3O+]

pH and pOH are related through this equation:

pH +pOH = 14
