Sect. Date Name Prelaboratory Assignment: Qualitative Analysis Group III Cations 1. Prepare a complete flow chart for the procedure and put it on your data sheet. 2. Write balanced net ionic equations describing each of the following reactions: Dissolution of Ni(OH), in nitric acid. Oxidation of Cr'to Cr by CIO in alkaline solution (CIO is converted to CI') The confirming test for Fe 3. A solution that may contain any of the group II cations. Treatment of the solution with...
Flowchart for unknown containing cations (Hg, Cd, Cr, Ni, Ba) Create a Flowchart for an unknown solution comtaining cations, Hg, Cd, Cr, Ni, Ba
I'm in serious need of help. I worked on the Qualitative Analysis of Cations Lab, Groups I and II. For group I, the possible Ions in a solution were Ag+1, Pb+2, Hg2+2. I was able to sucessfully percipitate out and confirm the presense of Silver. For Group II, the possible Ions were Hg2+, PB2+, Bi2+, Cu2+. The problem is I should have percipitated out three Cations and only found one. I know with certainty that I did not have Mercury...
make a flow chart to separate these ions Ag, Bi, Ni, Sb.

Part A.
Use the attached flow chart of a qualitative analysis separation
and identification scheme to answer the following question.
What ion is present in solution if the following observations
were seen (enter your answer as the chemical symbol without the
charge)
Addition of HCl: no precipitate
Addition of NH3/NH4Cl: a precipitate
forms
Addition of NaOH and H2O2: no
precipitate
Heat to remove H2O2 and addition of HCl: a
colorless solid is formed
Addition of HCl, Aluminon and NH3: a...
Lab 8: Qualitative analysis of cations Would you be able to distinguish between Cu2+ and Ni2+ ions in a solution if you added concentrated NaOH solution? What would you expect to happen? Write a balanced molecular and net ionic equation for both ions reacting with NaOH. Use Cu(NO3)2 and Ni(NO3)2 in your reactions for the respective ions. Show the correct phase of all species in the reaction for full credit.

QUALITATIVE ANALYSIS OF GROUP II CATIONS Qualitative analysis is a method for identifying the elements present in a unknown mixture. For this purpose, metal cations are broadly classified into three groups based upon their solubilities. Group I cations, Pb2+, Ag, and Hg22+ form insoluble chlorides. Group Il cations, Cu2+, B12+, Hg2+, Cd2+ Sn4+, Sb2+ form insoluble sulfides belowyph 0.5 Group III cations, Al3+, Cr3+.Co3t felt Mn2+, Ni2+, Zn2+ form insoluble sulfides above pH 9. Group IV cations, Ba 2+, Ca2+, Mg2+, Na+, K+, NH4+, are the...
Qualitative Analysis of Metal Cations Qualitative analysis can determine the metal cations that are present in a sample based on their solubility characteristics. One such scheme is shown in the flow diagram. Some ions that are soluble in all of the test solutions can still be identified based on flame tests. Certain ions impart characteristic color to the flame.Part AA solution contains some or all of the ions Cu2+, Al3+, K+, Ca2+, Ba2+, Pb2+, and NH4+. The following tests were performed, in...
