pH = pKa + log (base)/(acid)
Why not plug some number into the base and another number for acid and evaluate pH. If the number goes up you will have your answer and if it goes down you will have your answer.
The pK of acetic acid is 4.76. Which statement is true at pH 5.0?
[A^-] = [HA]
[A^-] < [HA]
