Q1. pH of Weak Acids (Medium)
You are provided with 0.10M Nicotinic acid (C6H5NO2).
The pH of the solution is 2.9. What is the degree of
dissociation?
Change initial concentration of Nicotinic acid to 0.010M.
What is pH and percent ionization? Given the Ka of
Nicotinic Acid is 1.7 x 10-5 M
Change initial concentration of Nicotinic acid to 0.001M.
What is the pH and percent ionization?
