The Total solution for NCERT class 6-12
The ionization constant of propanoic acid is1.32 × 10–5. Calculate the degree of ionization of theacid in its 0.05M solution and also its pH. What will be its degree ofionization if the solution is 0.01M in HCl also?
Letthe degree of ionization of propanoic acid be α.
Then,representing propionic acid as HA, we have:
Inthe presence of 0.1M of HCl, let α´ be the degree of ionization.
