Titratable Acidity

Titratable Acidity. The amount of acid (q.v.) that is present in a substance as determined by titration (q.v.). It is normally estimated by slowly adding a solution of sodium hydroxide, NaOH, of known strength to a sample solution of the substance whose acidity (q.v.) is to be determined until the point of neutrality is reached as indicated by a change in the color of an indicator dye (q.v.) contained in the sample solution.
