Tollens Reagent – 125ml Packs

Tollens Reagent is an ammoniacal silver coordination reagent widely recognized in chemical education for demonstrating organic functional group reactivity. It provides educators with a classical testing solution for exploring aldehyde oxidation in college and university teaching laboratories.

In undergraduate chemistry practicals, this reagent is predominantly employed to distinguish aldehydes from ketones. Upon warming with an aldehyde, the diamminesilver(I) complex is reduced to metallic silver, forming a mirror-like coating on the test tube, which provides students with an unambiguous visual demonstration of redox behavior and carbonyl classification.

This laboratory chemical is well suited for college laboratory curricula where supervised student practical work requires striking visual results. It reinforces theoretical classroom lessons on mild oxidation agents.

Because ammoniacal silver solutions must not be stored long-term, this reagent should be used promptly and test residues neutralized under instructor guidance. Always wear protective gloves and eyewear.
