ascorbic acid chemistry
« on: 21/08/2007 11:14:56 »
Does anyone out there in the chemistry field know why ascorbic acid although its called an acid is not actually an acid?
As well as that question if ascorbic acid was to react with iodine would the two alcohol groups be oxidided to carbonyls?

thanks

"is not actually an acid" meaning that you find no -COOH group(s) ?  There are more like that :  e.g. phenol (C6H5OH) used to be known as "carbolic acid"...
Each of the -OH functions can make it an acid, because it can set free a proton (H+), and there are number of salts.
Wikipedia will tell you more :  http://en.wikipedia.org/wiki/Ascorbic_acid and http://en.wikipedia.org/wiki/Phenol
