I understand that when there is no oxygen present the TTC and Methylene Blue 
will change colour however i dont understand how do they change colour.  I 
know that that they are re-dox indicators but am not sure about how the whole 
process works.  Please explain in detail so i can understand.  
Thank you Very much
