Running the Silver Mirror Test
Tollens reagent is used freshly made. A few drops of the sample are added to the reagent in a clean test tube, which is then warmed in a water bath. An aldehyde reduces the silver(I) ions to metallic silver, which coats the inside of the tube as a bright mirror, while the aldehyde itself is oxidised to a carboxylate ion. Ketones such as acetone leave the reagent unchanged, so no mirror forms.
Related Reagents for the Test
- Silver Nitrate — the silver salt from which Tollens reagent is prepared.
- Ammonium Hydroxide — ammonia solution that dissolves silver oxide into the silver-ammonia complex.
- Benzaldehyde — aromatic aldehyde that gives a positive silver mirror.
- Acetone — a ketone, run alongside as the negative sample.
Further carbonyl and sugar reagents are found in Chemistry Lab.
