(b) Which solution has a higher percent ionization of the acid, a 0.10M solution of HC2H3O2(aq) or a 0.010M solution of HC2H3O2(aq) ? Justify your answer including the calculation of percent ionization for each solution.

The percent ionization is higher for 0.010 M solution of

Explanation:

 cM           0M           0M

So dissociation constant will be:

a) Given c= 0.10 M and = ?

Putting in the values we get:

b) Given c= 0.010 M and = ?

Putting in the values we get:

The percent ionization is higher for 0.010 M solution of

it is b that is the answer.
