Acetic acid, HC2H3O2, and sodium acetate, NaC2H3O2 (this provides the acetate ion C2H3O2-), can be used to make an "acetate" buffer.
A) Does the acetate ion or the acetic acid increase when a strong acid is added to the buffer?
B) Is it the acetate ion or acetic acid that decreases when a strong base is added to the buffer?
Explain your answers.
