Product description
- 250.0 ml of 0.050 M ZnSO4 was passed through a column containing 6.0 g of the cation exchanger. The solution flowing from the column was collected in portions of 50.0 ml, in each portion the content of zinc ions was determined and the following concentration values (mol/l) were obtained: 1-0.008; 2-0.029; 3 - 0.038 4-0.050; 5-0.050. Determine the total dynamic capacity (mmol/g) of the cation exchanger.
