98. Solving a chemistry problem

Determine the static exchange capacity of the cation exchanger for NaCl (mol / g), if 1.025 g of air-dry cation exchanger in the H-form with a moisture content of 0.05% is filled with 100 ml of 0.1 M NaCl and for titration of 25 ml of the solution obtained after ion exchange, spent 11.40 ml of 0.1 M NaOH (K = 1.015). Write an ion exchange reaction on a cation exchanger.
