Limitations of Tollens’ Test
- There are some sugars which can be isomerized under alkaline circumstances, certain carbohydrates without an aldehyde group may give positive Tollens’ test.
- Silver nitrate is a hazardous chemical so when it comes in contact with skin or clothing, the color of the same will disappear. So it is recommended to wear gloves and also ammonia fumes must not be inhaled.

Tollens Test
Tollens Test, also known as the silver mirror test, is a chemical test that is used to detect the presence of aldehydes in a given organic compound. The test is based on a redox reaction between the aldehyde and Tollens’ reagent, which results in the formation of a silver mirror. Tollens’ reagent is widely used in organic chemistry for the qualitative analysis of organic compounds, especially in distinguishing aldehydes from other carbonyl compounds. The reagent used for the test is called Tollens Reagent which is an Ammoniacal Silver Nitrate Solution.
In this article, we will learn what is Tollens test, Tollens’ reagent, its reaction, its mechanism, and its applications.
