Procedure: B. Test for carbonate ion (CO,²) Add 1 mL of 1M Na2CO3 (or your unknown) and 1 mL of 6M HCI to a small test tube. C. Test for sulfate ion (SO,²) 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 BaCl2. D. Test for phosphate ion (PO4³) Add 1 mL of 0.5 M Na₂HPO4 (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 (HC2H3O2) to a small test tube. Now add 2 drops of 0.1 M Fe (NO3)3. A dark red solution indicates the presence of SCN-. F. Test for chloride ion, (Cl₂-) Add 1 mL of 0.5 M NaCl (or your unknown) and 1 mL of 6 M HNO3 to a small test tube. Next add 2 to 3 drops of 0.1 M AgNO3. G. Test for nitrate ion, (NO, Add 1 mL of 0.5 M NaNO3 (or your unknown) and 1 mL of 6 M NaOH 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 test tube. |
