The experiment that has the beautiful effect of a mirror surface forming on glass looks very impressive. Carrying out this reaction requires experience and patience. In our article you can read about the necessary reagents, how to prepare the equipment, and find out the chemical formulas of reactions.
The essence of the silver mirror reaction is the formation of metallic silver as a result of an oxidation-reduction reaction, in the interaction of an ammonia solution of silver oxide in the presence of aldehydes.

The reaction between Tollens reagent and aldehydes to form a silver mirror is a redox reaction. The aldehyde reduces the silver ions in the Tollens reagent to form elemental silver, which then deposits on the surface of the reaction vessel, creating a mirror-like appearance.
A silver mirror is formed by Tollens reagent due to the reduction of silver ions to metallic silver on the surface of the test tube. This reduction reaction occurs in the presence of an aldehyde, which acts as the reducing agent by donating electrons to the silver ions. As a result, a silver mirror is deposited on the inside of the test tube, indicating the presence of an aldehyde in the sample.
Benzil does not react with Tollens reagent because it does not contain aldehyde or ketone functional groups. Tollens reagent is a silver mirror test used for the detection of aldehydes in a sample by the reduction of silver ions to metallic silver. Benzil, being a diketone, does not undergo this reaction.
No, starch does not give a silver mirror test. The silver mirror test is used to detect the presence of aldehydes, not starch. Starch is a complex carbohydrate composed of glucose units linked together.
Lead is less reactive than silver on the reactivity series, so lead will not replace silver in a single displacement reaction. Silver will stay as it is in the reaction.

The dark spots on a mirror are the effect of the decomposition of silver nitrate (AgNO3) to silver (Ag).
A silver mirror is formed by Tollens reagent due to the reduction of silver ions to metallic silver on the surface of the test tube. This reduction reaction occurs in the presence of an aldehyde, which acts as the reducing agent by donating electrons to the silver ions. As a result, a silver mirror is deposited on the inside of the test tube, indicating the presence of an aldehyde in the sample.
Glycerol can give a positive result in the silver mirror test due to its ability to act as a reducing agent. In the presence of silver nitrate and an alkaline solution, glycerol reduces silver ions (Ag⁺) to metallic silver (Ag), forming a reflective silver mirror on the surface of the test container. This reaction occurs because glycerol has an aldehyde-like structure under certain conditions, which facilitates the reduction of silver ions.
Metals almost always gain electrons, it gives metals their positive(+) characteristic.
it is know as the silver mirror test, the overall half equation reaction is => CH2O + 2OH- ==> CH2O2 + H2O +2e- [Ag(NH3)2]+ + e- ==> Ag + 2NH3 CH2O + 2OH- + 2[Ag(NH3)2]+ ==> CH2O2 H2O + 2Ag +4NH3
Benzil does not react with Tollens reagent because it does not contain aldehyde or ketone functional groups. Tollens reagent is a silver mirror test used for the detection of aldehydes in a sample by the reduction of silver ions to metallic silver. Benzil, being a diketone, does not undergo this reaction.
The color of a mirror is typically silver or gray.
No, starch does not give a silver mirror test. The silver mirror test is used to detect the presence of aldehydes, not starch. Starch is a complex carbohydrate composed of glucose units linked together.
Glucose is the carbohydrate used commercially in the silvering of mirrors. It is used to reduce silver nitrate to silver metal in a chemical reaction that creates the reflective surface on the mirror.
A Silver mirror does not appear as ketones cannot be further oxidized unlike aldehydes in which a silver mirror does appear.
Lead is less reactive than silver on the reactivity series, so lead will not replace silver in a single displacement reaction. Silver will stay as it is in the reaction.
