Chemistry

Silver ion, Ag+, can be recovered from photographic solutions byadsorbing onto an ion exchange resin (Langmuir adsorption)

Ag+ +Ex↔ Ag-Ex logKL =12.30

(where Ex represents an adsorbing site on the resin). Accordingto the manufacturer, the resin has 1.20 x10-5 moles of adsorbingsites per gram of resin.

a) If you have a liter of solution with [Ag+] = 0.030 mM, howmuch resin will you need to adsorb all the silver assuming 100%binding?

b) Calculate the predicted equilibrium dissolved [Ag+] if youadd 10.00 g of resin to 1.00 liter of solution described in parta.
