Abstract Five methods for the determination of acidity of acid solutions of low concentration (down to .00001 mol/kg) were investigated. Four of the methods provide satisfactory results. Method (3), Gran's plot end-point detection using .001 m NaOH titrant, suffers from the inability to control exactly the size of reagent increments, which is essential for this method. Automated titration systems could remedy this deficiency.
