Lab: Creating a Redox Table

Purpose:
The purpose of this lab exercise is to construct a table of relative strengths of oxidizing and reducing agents. By completing this exercise, you will see how more extensive tables of relative strengths of oxidizing and reducing agents have been developed.

Procedure:
Using the results from the three tables below, prepare a single table of relative strengths of oxidizing and reducing agents.


Table 1. Reactions of metals and nonmetals with solutions of ions.
I 2(aq)
Cu2 + (aq)
Ag + (aq)
Br2 (aq)
