8 Which equation represents what happens when a small amount of strong base is added to the buffer?

OH- + A- A2- + H2O


OH- + HA A- + H2O


H3O+ + A- HA + H2O


H3O+ + HA H2A+ + H2O

Answer 1

I agree with his answer. It is correct. However do you think you can help me with a question?

Answer 2

The answer to this question is OH- + HA ⇒ A- + H2O. The conjugate acid in the buffer, HA, neutralizes added strong base, OH-.
