Acetic acid is then neutralized (the second jump), while the third jump corresponds to NH 4 Cl as the weakest acid. Figure 2. HCl is the strongest acids compared to acetic acid and ammonium chloride.

Conventional determination of the acetic acid content in water is done by titration, which is a slow, time-consuming process. ... All Abbemat refractometers from Anton Paar directly show the acetic ...

For the determination of the blank, 4 mL of formic acid and 50 mL of acetic anhydride are placed into a titration beaker. ... = 0.1 mol/L in glacial acetic acid until the equivalence point is passed.

50 to 75 mg of metformin hydrochloride is weighed accurately into a titration beaker to which 4 mL formic acid is added. After complete dissolution, 50 mL of acetic anhydride is added.
