71. Solving a chemistry problem

5. To 1.025 g of the cation exchanger in the H-form, the moisture content of which is 0.05%, was added 100 ml of 0.1 N NaCl solution. For titration of 25 ml of the resulting eluate, 11.4 ml of 0.1 N NaOH solution was used with a correction factor of 1.015. Compose an ion exchange equation and determine the exchange capacity of the cation exchanger for Na +.
