Three suggestion are made for ways to removes silver ions from solution: a. Make the solution 0.01M in Nal . b. Buffer the solution at pH = 13 . c. Make the solution 0.01M Na_(2)S . What will be the equilibrium silver ion concentartion in each case? which course of action is most effective in removing Ag^(o+) ions? K_(sp) (AgI) = 8.5 xx 10^(-17), K_(sp) (AgOH) = 2 xx 10^(-8) , K_(sp) (Ag_(2)S) = 5.5 xx 10^(-51)
