The oxidation state of Ag in tollen’s reagent isa)+1.5b)0c)+2d)+...
The silver-producing reaction in this demonstration is one that is commonly used in basic organic laboratory classes to identify aldehydes. The reaction called "The Silver Mirror Test" or Tollens' Test is accomplished by mixing aqueous silver nitrate with aqueous ammonia to produce a solution known as Tollens' reagent. Although this solution contains only a very weak oxidizing agent, it is strong enough to oxidize the aldehyde functional group. As this oxidation occurs, silver is reduced from the +1 oxidation state to metallic silver. This metallic silver is deposited on the walls of the test tube producing a reflective "mirror".

Tollens reagent is a mild oxidizing agent used to distinguish between aldehydes and ketones. It is prepared by dissolving silver nitrate in ammonia solution. The oxidation state of Ag in Tollens reagent is +1.
Explanation:
Tollens reagent is a solution of silver nitrate in aqueous ammonia. When Tollens reagent is added to an aldehyde, it is oxidized to a carboxylic acid, and silver ions are reduced to metallic silver. The reduction of silver ions to metallic silver is responsible for the formation of a silver mirror on the walls of the test tube.
The reaction can be represented as follows:
RCHO + 2Ag(NH3)2+ + 3OH- → RCOO- + 2Ag + 4NH3 + 2H2O
In this reaction, Ag+ is reduced to Ag, which means that the oxidation state of Ag in Tollens reagent is +1.
Therefore, the correct answer is option 'D', i.e., the oxidation state of Ag in Tollens reagent is 1.
