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)

  1. Sorry.... the tables not supposed to turn out liek that. Can anyone show me how the table can be improved?

    Table 1: 4 vertical columns, 4 horizontal columns (on top)

    Table 2: 4 vertical columns, 4 horizontal columns (on top)

    Table 3: 3 vertical columns, 3 horizontal columns (on top)


    Would it be possible if I scanned the table and sent it through as a jpg image?

  2. These boards have a problem with spacing, as you have just proved to yourself. I don't think you can scan an image into the page. We can't draw structures of compounds, either, but sometimes we can use ingenuity and rearrange them so we can draw them. I have seen them done this way and that might be something to play with; for example,
    Column 1...Column 2... Column3...Column 4
    I2(aq).....Cu^+2(aq)...Ag^+(aq)..Br2(aq)

  4. *Please note

    For table 1 I2(aq), Cu2+(aq), Ag+(aq) and Br2(aq) are supposed to be shifted to the right since they are horizontal.
    I-(aq), Cu(s), Ag(s) and Br-(aq) are vertical.



    For table 2
    Ag+(aq), Pb2+(aq), Cu2+(aq) and Zn2+(aq) are supposed to be shifted to the right since they are horizontal.
    Ag(s), Pb(s), Cu(s) and Zn(s) are vertical.



    For table 3
    Br-(aq), Cl-(aq) and I-(aq) are supposed to be shifted to the right since they are horizontal.
    Br2(aq), Cl2(aq) and I2(aq) are vertical.
