Title	: REDOX REACTION I

Aim	: To observe the changes that occur in Redox reactions

Apparatus : 
test tubes , rack , acidified potassium manganate VII , iron(II)solution , 
iron(III)solution , acidified potassium dichromate , acidified potassium iodide
potassium iodate solution , ethanol , aqueous iodine , sodium thiosulphate solution , 

Directions : 
Place each of the following reagents in test tubes and observe any colour changes
that occur . 
(please note that a colour change includes the original colour e.g. blue to red)

Test Tube	Reagents
1		acidified potassium manganate VII + iron(II)solution
2		acidified potassium manganate VII + iron(III)solution
3		acidified potassium manganate VII + sodium thiosulphate solution
4		acidified potassium dichromate + iron(II)solution
5		acidified potassium dichromate + acidified potassium iodide
6		acidified potassium dichromate + ethanol
7		acidified potassium iodide + potassium iodate solution
8		aqueous iodine + sodium thiosulphate solution
9		iron(III)solution + sodium thiosulphate solution

Note the colour of the first solution . Add the second and note any colour changes .
Write equations showing the rxns if any .
Which of the reagents were oxidized and which were reduced ? 
Therefore which are oxidizing agents ?
