A solution possibly contains Ag+, Pb2+, Bi3+, Fe3+, Ba2+ and Na+. You are about to begin the separation of the group I cations but no HCl is available. Would the following reagents be an acceptable replacement for separation of the group I cations in this sample? To justify your choice as yes or no, write the NIE for all precipitates you expect to form. If only group I solids are precipitating, that will be a “yes” and if more than the group I solids precipitate, that will be a “no.”

a) HBr b) HC2H3O2 c) NaOH d) NaI

    2) You are presented with an unknown that possibly has Ag-, Bi-, Sn+, Zn2+, Co2+ and Na'. You divide the solution into three equal volumes, labeling one "A," one "B," and one "C." To "A" you add 6 M HCl and do not observe any precipitate forming. In tube B, you add 6 M HCl until the pH is 0.5 then add thioacetamide and heat the solution in a hot water bath for seven minutes, eventually observing a black precipitate....
