Application Memo Boric Acid in Luster Nickel Plating Solution Industry Inorganic chemical industryInstrument Automatic potentiometric titratorMeasurement methodNeutralization titration 1. Overview After adding saturated potassium ferrocyanide solution， pure water and mannitol to thesample， boric acid concentration is measured by titration with 0.1mol/L sodium hydroxidesolution. The endpoint is the maximum inflexion on the titration curve. The boric acidconcentration is calculated from two data of titration volumes of the sodium hydroxide at theendpoints. 2. Apparatus Main unit Automatic potentiometric titrator (preamplifier STD) Electrode pH glass electrode Ceramic reference electrode Temperature compensation electrode 3. Reagents Titrant 0.1mol/L sodium hydroxide solution Solvent Pure water Additive Saturated potassium ferrocyanide solution， Mannitol 4. Example Sample Titer Conc.
