Qualitative Analysis Worksheet Page 3

Question 6: Use the data you have acquired in Parts A and B to complete the ﬂow chart below.

It will serve as a reference for identifying the cations in an unknown solution in Part C. (At each

branch in the ﬂow chart, you should list the ions that exist as solid compounds on the left, under

the label “precipitate #.” List ions that exist in solution on the right, under “supernatant.” There

should be from zero to three entries on each line. At the end, the ions should be separated and each

of the three ions should be present at diﬀerent places on the ﬂow chart.)

Question 7: Describe the location of each cation in the separation scheme and the conﬁrmatory

test used to conﬁrm the presence of that ion.
