Question
During the titration the following reaction occurs
HA + NAOH = NaA + H20
What is the concentration of A (the conjugate base of the weak acid) at the equivalence point?
M
Use [A]and the pH at the equivalence point to estimate Ka of the weak acid (this is the hard way of estimating Ka)
Use the pH at the half-way point to estimate K, of the weak acid (this is the easier way)
