Five different acids all with the same initial concentration and volume are each titrated with 1.5MBOH.
a. Which acid titration has the highest pH at the halfway point to equivalence?
HCl
HClO2 (Ka) = (1.1 x 10^(-2))
HNO2 (Ka) = (4.0 x 10^(-4))
C6H5(CO)OH (Ka) = (6.5 x 10^(-5))
HCN (Ka) = (6.2 x 10^(-10))
