Make a flow chart of the purification scheme for the following
scenario.
7. Benzaldehyde is used as the starting material for the
synthesis of cinnamic acid. An organic chemistrystudent had made
the mistake of stopping the reaction before it was complete and
ended up with a mixture ofbenzaldehyde and cinnamic acid. Purify
the cinnamic acid. Provide data to show your compound is pure.
Qualitative Analysis on how to separate these ions using a clear
and detailed flow chart: Ag+, Cu+2, Fe+3, Cr+3, Zn+2, Ba+2
The test reagents available are 3M HCl, 6M NH3, 6M NaOH, 3M
H2SO4, 3% H2O2, 15M NH3
The confirmatory test reagents available are: 6M acetic acid,
0.2M K4Fe(CN)6, and 0.2M KNCS
What inferences can be made? NaOH was added to a blue-green
solution (Fe3+, Ni2+, Mn2+,
Cr3+, and/or Zn2+). After stirring, the
solution appeared light green with no precipitate.
Draw a flow diagram that summarizes the separation of the
cations in these unknown: Pb2+, Mn2+, Bi3+, Ba2+, Cu2+, Mg2+.
At each step, give the correct chemical form of the cation(s)
present. Alsdo indicate observed colors of precipitates and
supernatants.
I need to identify the cations A through G as K+, Cu2+, Ag+,
Ba2+, Fe3+, Mg2+, or Pb2+
The unknown cation is Br-/OH-
From what I believed I've figured out is:
K+ = F
Cu2+ = A or E
Ag+ = B or C
Ba2+ = G
Fe3+ = A or E
Mg2+ = A or E
Pb2+ = D
I believe this may be correct but I am unable to figure out
Cu2+, Ag+, Fe3+, and Mg2+. I also...
Use solubility rules and other properties to separate the given
ions (Ba2+, Ag+, and Fe3+)
Ba2+, Ag+, and Fe3+ mixed in
one beaker. Real compounds dissolved:
Ba(NO3)2, AgNO3 and
Fe(NO3)3; 0.1 mol/L for all.
You may need to precipitate them
one by one.
HNO3, NaI, Na2SO4, NaOH,
NaHCO3, Na2CO3,
Na3PO4, filter paper, funnel, and Erlenmeyer
flasks are available to accomplish the task.
Three solid samples total should be obtained.
What is a procedure for separating the given ions?
