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. PbCl ? 2. Ag+ 3. ? 4. S1 Group 1, the Chloride Group BACKGROUND...
QUESTION 1 The procedure for testing your unknown solution in this week's lab is identical to the procedure which you conducted in Week 1. The only difference is, of course, your Unknown Solution may or may not contain all of the ions which you tested for in Week 1. With that being said, please consider the following scenario: You enter the lab and obtain an Unknown Solution from the Stockroom. You begin testing the solution through the steps outlined in...
What is the chemical reaction taking place here? I thought it was Zn(CN)2 but it is not a denim blue. The Soluble Hydroxide Group: Analyze the Solution for the Presence of Znº and All 25. To test for All, add 10 drops of 6 M HNO, solution to Test Tube 5. Check the pH of the solution. If it is not acidic, add more 6 M HNO, dropwise until the solution becomes acidic. Add 6 M NH, solution dropwise until...

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...

Write balanced net ionic equations for the following reactions: The precipitation of the chloride of Pb a. in Step 1. The formation of a yellow precipitate in Step 4. b. The formation of a complex ion in Step 5. c. d. The reaction that forms a white precipitate in Step 5....
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 concluded that my unknown was Pb2+. since yellow precipitate formed. can you help me answer the questions for the 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....
