TOLLEN'S SILVER MIRROR TEST FOR ALDEHYDES <br />
(6 of 7) <br />
Presence Shown By Metallic Silver Precipitation<br />
The silver ion is complexed with ammonia to form Ag(NH3)2+ (the Tollen's reagent). When the silver is reduced to metal by the aldehyde (dextrose) it precipitates out as a silver mirror on the reaction vessel.
