2. To determine the salt content in the solution, the method of ion-exchange chromatography was used. An aliquot of the analyzed CuSO4 solution with a volume of V(X)= 10.00 ml was passed through a chromatographic column with a strongly acid KU-2 cation exchanger in the H-form, and after washing the column with water, the collected eluate was titrated with a sodium hydroxide solution with a molar concentration c(NaOH)= 0, 1000 mol / l, while spending V (NaOH) \u003d 11.95 ml.
Write the equation for the ion exchange reaction between the cation exchanger (R-H) and the analyzed solution passed through the cation exchanger in molecular and ionic form. Calculate the titer (g/ml) of the salt in the analyzed solution.
