o-Phthalic acid is proposed as a standard substance for buffer solutions of known hydrogen ion concentration (I < 0.2 M KCl, p[H+] = 3.0-5.4, 25Β°C). Its crystallinity, purity and slightly wider buffer range afford advantages over acetic acid. Empirical relationships between measured pH (pH,) and cal
