In qualitative analysis of anions - carbonate ion, sulfate ion , phosphate ion, thiocyanite ion, chloride ion , and nitrate ion . Write the chemical reactions and answer these questions.

Write the chemical reactions involve in the experiment.
Guide Questions
1 All nitrates are soluble. What is it about HNO3 that enables this reagent to
differentiate among the precipitates formed by different anions reacting with AgCI?
2. No reaction occurs when you add HCI to an aqueous solution of your saltunknown.
What can you conclude from this outcome?

Procedure:
B. Test for carbonate ion (CO,?)
Add 1 ml of 1M Na,CO: (or your unknown) and1 ml of 6M HCI to a small test
tube.
C. Test for sulfate ion (SO,)
Add 1 ml of 0.5 M Na,SO. (or your unknown) and 1 ml of 6 M HCI to a small
test tube. Next add a few drops of 1 M Baclı.
D. Test for phosphate ion (PO, *)
Add 1 ml of 0.5 M Na;HPO. (or your unknown) and 1 ml of 6 M HNO3 to a
small test tube. Next add a 1 ml of 0.5 M (NH4),MoO, and stir thoroughly. Place
the test tube in the hot water bath and continue to stir.
E. Test for thiocyanate ion, (SCN)
Add 1 ml of 0.5 M KSCN (or your unknown) and 1 ml of 6 M acetic acid
(HC,H;O2) to a small test tube. Now add 2 drops of 0.1 M Fe (NO:)3. A dark red
solution indicates the presence of SCN-.
F. Test for chloride ion, (Cl-)
Add 1 ml of 0.5 M NaCI (or your unknown) and 1 ml of 6 M HNO; to a small
test tube. Next add 2 to 3 drops of 0.1 M AGNO:.
G. Test for nitrate ion, (NO, )
Add 1 ml of 0.5 M NANO: (or your unknown) and 1 ml of 6 M N2OH to a small
test tube. Then add a few granules of aluminum metal and put the test tube in
the hot water bath. Place a red litmus paper directly above the testtube.
