Determination of the exact concentration of the HCL titrant We recommend ready to use HCl titrant. The exact concentration of the HCL 1.000 mol/l can be determined using the titrimetric standard Tris hydroxy amino methane (TRIS). The standard can be dried for 24 h in an exsiccator at room temperature. 1-2 g of the standard are weighed accurately in a 150 mL beaker and dissolved in 80 mL of dist. water with stirring. It is titrated with the 1 mol/l HCl solution. Repeat the standardization two times. The average value is stored automatically in the exchangeable unit.
