Narrative; Aqueous solutions of glucose, silver nitrate plus A silver mirror soon coats the flask as the Ag(I) ion is reduced to Ag metal and glucose is oxidized to gluconic acid. ... Discussion; A silver mirror coats the flask because the Ag(I) ion is reduced to Ag(0) as Ag(I) oxidizes glucose to gluconic acid.

Tollens reagent: Into a test tube which has been cleaned with 3M sodium hydroxide, place 2 mL of 0.2 M silver nitrate solution, and add a drop of 3M sodium hydroxide. Add 2.8% ammonia solution, drop by drop, with constant shaking, until almost all of the precipitate of silver oxide dissolves.

The Tollens' test is important in carbohydrate chemistry, for proof of structure. The test is specific for reducing sugars. Fructose is also capable of reducing Tollens' solution, and is thus classified a "reducing sugar".

After posting the question reguarding Tollen's test reducing a keytose, it occured to me (after consulting the book) that Tollens reagent also reduces a alpha hydroxy keytone to 2 adjacent keytones. Since a keytose is an alpha hydroxy keytone it would be reduced.

The very different works of German artists Michael Toenges and Peter Tollens at Sweetow invite us to test this proposition. ... These found supports have the effect of seeming to take Tollens' painting process back to some originating point of abstraction. A number of his pieces, touching a postmodern fear,

From mud to mirrors: Complex ion equilibria and Tollen's Test ... This test is commonly used in organic chemistry to distinguish ketones, where the carbonyl carbon is bonded to two carbons, from aldehydes, where the carbonyl carbon is bonded to a carbon and a hydrogen.
