If A Dark Grey Precipitate Or Silver Mirror Forms On The Bottom And Sides Of The Test Tube.

What is a tollens reagent? It indicates the given sample contains reducing. A positive result will cause a silver mirror to form on. Pregnancy tests can read positive as.

This Test Is Named After The German Chemist.

A tollen test is performed to determine the presence of an aldehyde or a ketone in a given unknown solution. A positive test shows a. A small amount of silver nitrate is added to a test tube of the substance being tested. Alpha hydroxy ketones can cause a positive tollens’ test because they can tautomerize to aldehydes, and the aldehyde causes the tollens’ test to be positive.
