Question

Please put the following steps in order for the general procedurefor testing anions. Be sure to clean and then rinse your teststubes with distilled water before starting, when you get a freshsample of anion solution or are done for the day. To determinewhich of the three possible cations (sodium, potassium, or lithium)are in the anion unknown you must do a flame test as was done inexperiment 2.

1 2 3 4 5 Finally dispose of all used chemicals in the waste bottlefor exp. 5 in the fume hood and wash glassware.

1 2 3 4 5 To anion solutions that form a precipitate with 0.1Msilver nitrate add 0.5 mL of 6M nitric acid, observe and mixwell.

1 2 3 4 5 Test the unknown for the anion analysis (5B-xxxx) usingthe same tests and logic used for the known anion solutions.

1 2 3 4 5 Test fresh samples of anion solutions that did not reactwith 6M HCl or 0.1M barium nitrate by adding 0.5 mL of 0.1M silvernitrate, observe and mix.

1 2 3 4 5 Observe while adding 0.5 mL of 6M HCl to 1 mL samples ofthe anion solutions and then add 5 drops of 0.1M barium nitrate andobserve again.
