Titratable acid
In chemistry, Titratable acid generally refers to any acid that can lose proton in an acid-base reaction.
The term is used slightly differently in other fields. For example, in renal physiology, Titratable acid is a term to describe acids such as phosphoric acid, sulfuric acid which are involved in renal physiology. It is used to explicitly exclude ammonium as a source of acid, and is part of the calculation for net acid excretion.
It gets its name from the use of NaOH in acid-base titration to estimate the quantity of titratable acid.
