What is the pH of a solution that results from mixing together equal volumes of a 0.160 M solution of acetic acid and a 0.080 M solution of sodium hydroxide?

Solutions

Expert Solution

                         CH3COOH (aq) + NaOH(aq) ------------> CH3COONa(aq) + H2O(l)

I                       0.16                         0.08                                    0

C                     -0.08                       -0.08                                    0.08

E                     0.08                          0                                          0.08

                             PKa of CH3COOH = 4.74

    PH    = PKa = log[CH3COONa]/[CH3COOH]

              = 4.74   + log0.08/0.08

                 = 4.74 + log1
