The purpose of this lab was to identify the anions present in a mixture of solutions using qualitative analysis.

 

Anion anylisis is similar to cation analysis because separations are not usually required. In the experiment we analyzed 4 solutions with common anions:

 

(PO4)3-  (Phosphate)

Cl-  (Chloride)

(SO4)2-  (Sulfate)

NO3-  (Nitrate)

 

We performed the experiment with the four common anions, while ensuring that complete separation and precipitation occurred. Otherwise, the unreacted ions may interfere with the following reactions.
