1,4-dioxane. Fill approximately 500 ml of dioxane in a 1 000 ml volumetric flask. Add the capacity of an ampoule for the preparation of 0,1 mol/l perchloric acid standard volumetric solution. Make up to the volume with 1,4-dioxane. For the determination of the concentration of the perchloric acid standard volumetric solution, weigh about 0,18 g of dried potassium hydrogen phthalate to the nearest 0,1 mg into the titration beaker and dissolve in about 100 ml of acetic acid. Switch the stirrer on, immerse the electrodes and titrate with the perchloric acid standard volumetric solution beyond the potential jump. Calculate the concentration, fc, of the perchloric acid standard volumetric solution, in moles per litre, using the Equation (1): V
Mm = fc××10000 (1) where m0 is the mass of potassium hydrogen phthalate, in grams; M is the molar mass of potassium hydrogen phthalate (M = 204,23 g/mol); V is the volume, in millilitres, of perchloric acid standard volumetric solution consumed to the inflection point. 5 Apparatus Ordinary apparatus and the following. 5.1 Automatic potentiometric
