Determination of the exact concentration of the KOH titrant We recommend ready to use KOH titrants. The exact concentration of the KOH 0.1 mol/l can be determined using the titrimetric standard potassium hydrogen phthalate. In a 150 mL beaker, 0.2 g of the standard are weighed accurately and dissolved in 80 mL of dist. water with stirring. It is titrated with the 0.1 mol/l KOH solution. Repeat the standardization two times. The average value is stored automatically in the exchangeable unit. ChemTron Titroline 6000自动电位滴定仪 优莱博 TitroLine 7500KF容量法卡式水份滴定仪 优莱博 TitroLine 6000自动电位滴定仪
