96. Solving a chemistry problem

44. 500 ml of 0.05 N were passed through a column with 5 g of cation exchanger. calcium salt solution. When determining the Ca2 ion in portions of 50 ml, the following concentrations were obtained (g-eq / l): 0.003; 0.008; 0.015; 0.025; 0.04; 0.05. Determine the dynamic capacity of the cation exchanger for Ca2. Answer: 1.59 mg-eq / l.
