 Calculate the percent ionization of a 0.15 M benzoic acid solution in pure water and also in a solution containing 0.10 M sodium benzoate. Why is the percent ionization so different in the two solutions? 


Expert Answer

Step 1

Benzoic acid is a weak acid.  So its dissociation can be represented by ICE table.
