Lecture two Acid – Base Equilibria & pH Calculations
According to the Bronsted-Lowry theory, an acid is a proton donor and a Base is a proton acceptor.
Weak Acid: For Acetic Acid: HOAC
Ka =
Or We can write also for Weak acid:
Weak base: For NH3:
=Kw / Ka
Buffer Capacity (β )
For Weak base and it is salt:
For Salts of weak bases: (NH4Cl)
