Sankalp Tollens Reagent for Laboratory Usage, E3-8V4R-ILVN (Bottle of 100 ml)

Sankalp Tollens Reagent for Laboratory Usage, E3-8V4R-ILVN (Bottle of 100 ml) is a chemical reagent used to detect the presence of reducing sugars, such as glucose, in a solution. This test is based on the reduction of silver ions (Ag⁺) to form a silver mirror on the inner surface of a test tube or another container, indicating the presence of reducing sugars. The Tollens' reagent is named after the German chemist Bernhard Tollens, who developed it in the 19th century.

Key components and reactions involved in Tollens' reagent test:

Silver Nitrate (AgNO3): The primary component of Tollens' reagent is a solution of silver nitrate, AgNO3. In this solution, silver ions (Ag⁺) are present, making it sensitive to the presence of reducing agents.

Ammonia (NH3): To maintain alkaline conditions, ammonia is added to the silver nitrate solution. Ammonia acts as a complexing agent, which helps stabilize the silver ions and promote the reaction.

Sodium Hydroxide (NaOH): In some formulations of Tollens' reagent, sodium hydroxide (NaOH) is used instead of ammonia to maintain alkaline conditions.

The reaction occurs as follows:

The reducing sugar in the solution, typically glucose, reacts with Tollens' reagent in the presence of heat. Glucose is oxidized to form gluconic acid.
The silver ions (Ag⁺) in the reagent are reduced by the glucose to form silver metal (Ag) as a precipitate.
The silver metal then forms a reflective mirror-like coating on the inner surface of the test tube.

Tollens' reagent is commonly used to detect the presence of reducing sugars in various applications, such as food testing (for sugar adulteration), clinical diagnostics (for urine analysis), and chemical analysis. It's important to note that non-reducing sugars, such as sucrose (table sugar), will not give a positive test because they do not have the free reducing aldehyde or ketone groups necessary for the reaction. Additionally, while Tollens' reagent is a sensitive test, other tests, such as Benedict's or Fehling's solution, can also be used to detect reducing sugars.
