ANAL 364 The Chemisery and Qualiative Analysis of Cations Group Separaions and Separations of Group 1 Catioms 27 Post-Laboratory Questions (Use the spaces provided for the answers and additional paper if necessary.) 1. What are the properties of the Group I, I1, and I cations that permit their separation by groups? (2) The precipitate was separated from the supernatant liquid in (1) and was found to be insoluble in hot water. The precipitate turned grey-black upon addition of 6M NH,...

I need help with questions 4 and 7 please
1 Cation Analysis Prelaboratory Questions DIXON No.2 HB 1. Ag, Hg2+, and Pb2+ belong to group I cations. What specific reaction do they all undergo? What is the distinctive observation for this reaction? The observation, that they will occur is that a white preciptate will form. They will react with dilluted HCl. 2. Describe the solubility of compounds AgCl, PbCl2, and HgCl, in a) room temperature water. AGCI PbCl₂ insluable HgzCl₂...

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....

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...
