Oxidizing And Reducing Agents Lab Assignment

Purpose
The purpose of this lab assignment is to test multiple solutions by adding them to manganese in order to observe how they affect the reduction of manganese.
Question
How will different solutions (acid, neutral, basic) affect the reduction of Manganese?
Materials
● Bottle containing KMnO4
● Flask containing 10 M of H2SO3
● Flask containing 10 M of NaOH
● 4 x 600 ml beakers
● Carboy of ddH2O
Procedure
1. In a 600 ml beaker, create an aqueous solution of 0.01 M KMnO (be sure to explain how this is done and show your calculations in the materials and methods section). Right click on the beaker and select rename. Rename it “0.01 M KMnO4”.
2. To one of the beakers, add 100 ml of 10 M H2SO3 and 100 ml of 10 M NaHSO3. Note the pH. Label this beaker “acidified”
3. To another beaker, add 200 ml of 10 M NaHSO3 (use two of the flasks). Label this beaker “control”. Note the pH.
4. To the third beaker, add 100 ml of 10 M NaOH and 100 ml of 10 M NaHSO3. Note the pH. Label this beaker “basified”
5. Add 100 ml of 0.01 M KMnO4 to each of the three beakers.
6. Make any observations that are relevant-- qualitative and quantitative. Remember to use the panel to the side for aqueous species data, and remember to click on “solid” and note the mass of any solid species that may have evolved.
