Known and unknown report
Qualitative Analysis: Group I Cations 10 ORECTIVES A Leam some chemistry of Group I cations, R Analyze an unknown for Group I cations. THEORY AND DISCUSSION Group I cations are precipitated as insoluble chlorides: Ag, Pb, Hg2 +Cr-AgCl, PbCh, HgCla The colors of the following species will be helpful in the analysis for Group I cations....

I need help figuring out the flowchart and if I have the right
answers for the prelab please and thank you!
Group I, the Chloride Group BACKGROUND The precipitating reagent for the chloride group is chloride ion in an acidic solution. Only three of the 18 metal ions form a precipitate with this reagent: silver ion (Ag'), mercury(I)ion (Hg). and lead ion (Pb). Since lead chloride is somewhat soluble, it is not completely precipitated here, and a low concentration of...

I need help with the prelab and the flowchart. I’m totally
clueless on the flowchart.
For the prelab questions I have some answers but I don’t know
if they’re right. If they’re wrong, I would greatly appreciate an
explanation for the correct answer. I’m really trying to learn the
material but it’s hard now that classes are cancelled so I’m sorry
if these are dumb

1. For each of the descriptions of different solutions, what inferences can be made? (Which ion(s) are identified as possibly present, confirmed present, absent, or no conclusion?) a. Hot water was added to a white precipitate (AgCl and/or PbCl2). After stirring, the precipitate completely dissolved forming a colorless solution. b. Aqueous ammonia was added to a solution (Cu2+ and/or Bi3+). After stirring, a white precipitate formed, with a colorless solution above it.b. c. HCl was added to Group 1 and...
