WebJan 25, 2024 · Where pH measures the dissociated “free” hydrogen ions in the balance of acids and buffers in a solution, TA approximates the amount of total acidity, associated or dissociated, by measuring how much of a strong base (generally sodium hydroxide) it takes to reach an endpoint of pH 8.2. ADVERTISEMENT WebJun 20, 2024 · Titratable acidity is the acidity of a juice, must or wine determined from the amount of base needed to titrate the wine to a specific end point pH. Usually sodium hydroxide (NaOH) is used for titration to an end point pH of 8.2 in the US and 7.0 in France. Titratable acidity is reported in g/L tartaric acid equivalents and often abbreviated as TA.
