Acidity (see Section 3.7) is determined simply by, titrating hydrogen ion, with base. Titration to the methyl orange endpoint (pH 4.5) yields the “free acidity” due to strong acids (HCl, H2SO 4). Carbon dioxide does not, of course, appear in this category. Titration to the phenolphthalein endpoint, pH …
