Question 12.63 (Sixth Edition)

Postby Steve Magana 2I » Sun Jan 27, 2019 11:33 pm

Question: 12.63 The percentage deprotonation of benzoic acid in a 0.110 m solution is 2.4%. What is the pH of the solution and the Ka of benzoic acid?

How do you go from deprotonation percentage to pH? Thank you!

Deprotonation is the ratio of the concentration of deprotonated molecule over the initial concentration of the acid. With these concentrations and a Ka value, you should be able to solve for H30+ ion concentration to find pH
