Use the applet below to test an unknown sample which contains one type of anion. You can practice with known samples from the solid reagent jar. You can attempt a "true unknown", but only those students in classes officially using this applet can have their instructor or teaching assistant check their analysis.

ANION ANALYSIS; OBJECTIVES FOR THE EXPERIMENT; The student will be able to do the following: 1. Write a general description of the qualitative analysis technique for identification of unknown substances. 2. Plan a procedure for the analysis of an unknown solution of an anion and describe that procedure with a flow chart.
