Enačba oksidacije aldehidov s Tollensovim reagentom (NCSU – Dept. of Chemistry – Lecture Demonstrations, Tollen’s Test (Silver Mirror)).

RCHO + 2Ag(NH 3 ) 2 OH → RCOOH + 2Ag + 4NH 3 + H 2 O

- NH

+

RCOOH + NH 3 → RCOO

Po končanem poskusu odpadne snovi ne zavržemo v odtok , pač pa jih zberemo v posebni posodi za kasnejši odvoz nevarnih odpadkov. Pomembno je , da reagent takoj po uporabi uničimo. Dodatek kisline prepreči nastanek eksploz ivnega srebrovega nitrida. Viri Dharavath, A. (2022). Tollens reagent . Aldehydes Ketones Carboxylic Acids, Chemistry.
