A solution contains either Ag+(aq) or Fe3+(aq). Which chemical reagent would NOT allow you distinguish which cation is in the unknown?
A. C2O42-
B. HCl
C. KSCN
D. HNO3
E. all of these reagents would work to distinguish the ions
Homework Answers
Correct option is : (D.) HNO3
Explanation
HNO3 is a strong acid which dissociates to give nitrate ions NO3-
Nitrate ions does not form precipitate with either Ag+ or Fe3+
Hence, we cannot distinguish between these two ions.
C2O42- forms precipitate with Ag+
HCl forms precipitate with Ag+
KSCN forms precipitate with Ag+

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...

you are a hired consultant for a mining company whose ore contains a mixture of silver salts, including Ag2CO3, Ag2S, and Ag3PO4. The plan to dissolve the silver salts into solution with acid, and then use electrochemistry to transform the silver cation [Ag^+] into silver solid. What acid should they use to dissolve the silver salts in order to minimize undesirable side-reactions? Commercially available acids: HCl(aq), HBr(aq), HNO3(aq), H2SO4(aq) or "all these would work"

Review equation 16.10 and step B2. Ag+1(aq) and NH3(aq) will form a soluble complex ion. Use rule 3 of Water-Insoluble Salts in Appendix E to determine what would happen if Ag+1(aq) was combined with KOH instead of NH3. Write the net ionic equation with phase subscripts, where K+1 is a spectator ion which is cancelled out. Equation 16.10: Ag^+(aq) + Cl^-(aq) ⇄ AgCl(s) ⇅ 2NH3(aq) [Ag(NH3)2]^+(aq) Step B2: Silver Chloride equilibrium. To the clear solution from part B.1, add 5...

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....

Suppose you have a solution that contains 0.0480 M Ca2 and 0.0910 M Ag . If solid Na3PO4 is added to this mixture, which of the following phosphate species would precipitate out of solution first? When the second cation just starts to precipitate, what percentage of the first cation remains in solution? Na3PO4?or Ag3PO4? or Ca3(PO4)2? When the second cation just starts to precipitate, what percentage of the first cation remains in solution?
