But isn't Glucose ( C6H12O6 )oxidized to Gluconic Acid ( C6H12O7 ) ?
I used to think so, but it doesn't fit the experimental observation.
Every time I make colloidal silver with glucose based agents, it evolves a gas as evidenced by the bubbles which collect on the sides of my bottles. Where does the gas come from? It cannot come from making gluconic acid, so something different must be occurring.
There is no gas evolved if the glucose oxidizes to gluconic acid, so that reaction cannot be correct
under the conditions we use to make colloidal silver.To observe the gas production, make 20 ppm ionic silver cold, add corn syrup, heat to about 140F, and set the bottle aside. 30 minutes later, you will see tiny bubbles collected on the sides of the bottle.
But whether you make xylitol (or one of its cousins) or gluconic acid, the number of electrons transferred is the same.
Its also possible that both are true, and that the gluconic acid is an intermediate reaction. I have no way to tell. I have seen the reaction leading to C

5 listed as a possible reaction in a journal though.
Edited to add:
I refound the reference to the oxidation of glucose resulting in CO
