FREE Expert Solution

We are being asked to determine the percent ionization of

A. 8.0×10−3 M butanoic acid (Ka=1.5×10−5

B. 8.0×10−3 M butanoic acid in a solution containing 8.0×10−2 M sodium butanoate.


We will do the following steps to solve this problem:

Step 1: Construct ICE Chart

Step 2: Ka expression

Step 3: Determine [H3O+]

Step 4: Calculate the percent ionization

% ionization = [H3O+][HA]initial×100
