The empirical formula of a commercial ion exchange resin

Asked by admin @ 23/08/2021 in Chemistry viewed by 302 People

The empirical formula of a commercial ion exchange resin is C8H7SO3Na. The resin can be used to soften water according to the reaction Ca2+ + 2C8H7SO3Na ---> (C8H7SO3)2Ca + 2Na + .

What would be the maximum uptake of Ca2+by the resin expressed in mole/g resin?

Answered by admin @ 23/08/2021

From the reaction we get that,
2 moles of resins uptake 1 mole of Ca
i.e. 206 * 2=142 g of resins uptake 1 mole of Ca.
Thus the uptake capacity of resins = 1/142=0.00246
