R ter shift We will begin the anion analysis with a known solution containing I-, Cl-, and SO42-. First, we add aqueous silver nitrate to the known anion solution and the separation begins. Figure 3 presents an overview of the analysis. In Step 1, I- is confirmed; in Step 2, Cl- is confirmed; and in Step 3, SO42- is confirmed.
