Product description
- A portion of CaCl2*nH2O weighing 1.1246 g was dissolved in a volumetric flask with a capacity of 100 cm3. 10.00 cm3 of the resulting solution was poured into a column with an H-form cation exchanger, the static exchange capacity of which was 4.8 mmol-eq/g. Then the column was washed with water. For titration of the entire eluate, 15.40 cm3 of a 0.1 N NaOH solution were used with a correction factor of 1.020. Determine the composition of calcium chloride crystalline hydrate and the mass of dry cation exchanger required for the analysis of the entire sample.
