Question

Quizplus · Accepted Answer

The Tollens' test uses a silver mirror to detect the presence of aldehydes. The silver ions in the Tollens' reagent are reduced to elemental silver, which forms a silver mirror on the inside of the reaction vessel. This reduction is only possible with aldehydes, and not other carbonyl compounds such as ketones, because aldehydes are easily oxidized to carboxylic acids. Therefore, the element that causes oxidation in the Tollens' test is silver (Ag).
