If there are some group I ions mixed in with group II ions
together,
1. what would happen when you follow the procedures of adding
thioacetamide and heat in boiling water bath? (HInt: check the Ksp
of group I ions with sulfide)
2. How would you separate the two groups of ions and identify the
ions qualitatively? (Hint: some procedures are in the manual for
groups I and II)

I need help with the prelab and the flowchart. I’m totally

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

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...

Question 7 0.77 pts Title q7a7 Which of the following pairs of species, when mixed together in water in proper ratios, would provide a buffer solution? Think each pair through very carefully in terms what species will form when they dissolve in water, and how they can then (potentially) react with water Refer to the table of strong acids/bases on the exam information sheet if you don't have them memorized yet.
