Problem: A 0.077 M solution of an acid HA has pH = 2.16. What is the percentage of the acid that is ionized?

FREE Expert Solution

We are being asked to determine the percentage of the acid that is ionized.


Recall that the percent ionization is given by:

% ionization = [H3O+][HA]×100


We are going to do the following steps:

Step 1: Calculate [H3O+]

Step 2: Calculate % ionization
