Calculate the percent dissociation of butanoic acid (C3H2CO2H) in a 1.4 mM aqueous solution of the stuff.

The percent dissociation of butanoic acid is 9.8%

Explanation:

 cM                                                0             0

So dissociation constant will be:

Give c= 1.4 mM = and = dissociation constant  

Putting in the values we get:

Thus percent dissociation of butanoic acid is 9.8%
