WebbThe Kaof this acetic acid solution was 4.27x10 -5 and found by using the inverse of the pKa formula which is K a=10 -pKa all calculations are in the post lab. This is a weak acid due to the fact that lower K a’s yield a weaker acid. If this was a strong acid, the solution would dissociate completely and thus would have a much larger Kavalue. kacher manush release date
