I am trying to find out the amount of ascorbic acid present in juice, and 
I have read all of the questions you have answered about ascorbic acid, 
and I have a few questions..
If I titrate an iodine solution against the juice with some starch 
solution in it, is it a redox titration? 
If so, how do I write the redox equation? 
Does it go something like this? 
I2 + C6H8O6 --> 2I-  + ????
Thanks...
