A solution containing a mixture of metal cations was treated as outlined. Dilute HClHCl was added and no precipitate formed. H2SH2S was bubbled through the acidic solution. A precipitate formed and was filtered off. The pH was raised to about 99 and H2SH2S was again bubbled through the solution. A precipitate formed and was filtered off. Finally, sodium carbonate was added to the filtered solution and no precipitate formed. What can be said about the presence of each of these...

Qualitative analysis is a method for identifying the elements present in a unknown mixture. For this purpose
QUALITATIVE ANALYSIS OF GROUP II CATIONS Qualitative analysis is a method for identifying the elements present in a unknown mixture. For this purpose, metal cations are broadly classified into three groups based upon their solubilities. Group I cations, Pb2+, Ag, and Hg22+ form insoluble chlorides. Group Il cations, Cu2+, B12+, Hg2+, Cd2+ Sn4+, Sb2+ form insoluble sulfides belowyph 0.5 Group III cations, Al3+, Cr3+.Co3t felt Mn2+, Ni2+, Zn2+ form insoluble sulfides above pH 9. Group IV cations, Ba 2+, Ca2+, Mg2+, Na+, K+, NH4+, are the...

Fill out the chart please.
Now let us work on the left-hand branch of the flow chart containing the supernatant with the remaining four catto Cr. zn.NP, Mg(note, the presence of Nat should have already been flame tested, its presence here will not interfere with subsequent tests on the remaining ions.) We should keep in mind that our unknown could contain any number of these ions and thus we will need a procedure (flow chart) that can help us separate...

Find the best reducing agent from Cu+, Ag+ F2 and Fe3+
#1. In the reduction table i can see several repeated values of
Fe3+ one is equal to 0.77v and the second one is equal to -0.036v
so, which one do I choose? Please explain.
#2.If I'm asked to find the best oxidation agent, from the
values already provided (Cu+, Ag+ F2 and Fe3+) which one would it
be? and how would I decide from repeated values, like in #1,...
