1. For each test tube - #3, #4 and #5 - record the following results of the reactions:



 

 

Tube #3

Tube #4

Tube #5

a

Color of the solution

  

 

 

  

 

b

Color of the precipitate, if any

 

 

  

 






2. Based on these results, to what oxidation states did the Mn change in each test tube?


 

 

Mn

a

Test tube 3  

 

b

Test tube 4

 

c

Test tube 5  

 






3. Write the net ionic equations for the redox reactions in each test tube:
Referring to the table in the background of the lab manual may be helpful.


a

Test tube 3  

 

b

Test tube 4

 

c

Test tube 5
