Acetic Acid Buffer Changes in Titration

Acetic acid buffer changes during a weak acid–strong base titration. When acetic acid is titrated with sodium hydroxide, the reaction forms water and the conjugate base of the acid, sodium acetate. The mixture of acetic acid and sodium acetate acts as a buffer, which helps show how solution makeup shifts during the titration...

Recall that the titration of acetic acid with sodium hydroxide produces sodium acetate and water, resulting in a buffer.

The relative concentration of the different species in the buffer solution during various points of the titration is indicated by the alpha values.

While the curved line represents titration of acetic acid and so...
