How is tollens reagent prepared in molecular formula?
Tollens reagent, a solution of silver nitrate (AgNO3), ammonia (NH3), and sodium hydroxide (NaOH), can be represented by the formula [Ag(NH3)2]+. To prepare Tollens reagent, silver nitrate is mixed with ammonia until the precipitate dissolves, and then sodium hydroxide is added to form the [Ag(NH3)2]+ complex ion.
What are the components of tollens reagent?
Tollens reagent is composed of silver nitrate solution, ammonia solution, and sodium hydroxide solution. Silver ions in the solution are reduced to silver metal, forming a silver mirror on the inside of a test tube when aldehydes are present.
Why can't you prepare and store tollens' reagent in advance for tests?
Tollens' reagent is made by mixing two solutions - silver nitrate and ammonia - right before use because the reaction is sensitive to light, air, and temperature, which can degrade the reagent quickly. Preparing it in advance may lead to a loss of effectiveness, affecting the results of tests. Therefore, it is best to prepare Tollens' reagent fresh when needed for accurate testing.
What is the oxidation number on Ag in the compound AgCl?
The oxidation number of Ag in AgCl is +1. AgCl is an ionic compound where Cl has an oxidation number of -1, so for the compound to be neutral, the oxidation number of Ag must be +1.
Equation for the reaction of ethanal with Tollens reagent?
Well, darling, the equation you're looking for is: CH3CHO + 2[Ag(NH3)2]+ + 3OH- → 2Ag + CH3COO- + 4NH3 + 2H2O. It's a fancy way of saying that ethanal reacts with Tollens reagent to form silver, acetate, ammonia, and water. So go ahead, impress your chemistry buddies with this little gem.
What is formula of tollens reagent?
2[Ag(NH3)2]OH is tollen's reagent
What is the equation for the reaction between tollens' reagent and butanone?
The reaction between Tollens' reagent (Ag(NH3)2+) and butanone forms a silver mirror on the inner surface of the reaction vessel. The equation for this reaction is: Ag(NH3)2+ (aq) + 2e- -> Ag(s) + 2NH3(aq)
what is the outcome of tollens reagent reacting with methanal, ethanol and propanone?
The outcome of the Tollens reagent reacting with methanal (formaldehyde), ethanol (ethyl alcohol), and propanone (acetone) is the formation of metallic silver (Ag) in the case of methanal, while ethanol and propanone do not show a significant reaction with Tollens reagent. Tollens reagent is used as a chemical test to distinguish between aldehydes and ketones, where aldehydes react to produce a silver mirror, while ketones do not react.

What is the oxidation number of AgNO3?
In Ag NO3 the oxidation number of Ag (Silver) is 1+, the oxidation number of N (Nitrogen) is 5+, and the oxidation number of O (Oxygen) is 2-.
What is the oxidation number for agno3?
In AgNO3, silver (Ag) has an oxidation number of +1, nitrogen (N) has an oxidation number of +5, and oxygen (O) has an oxidation number of -2. This is because the overall compound is neutral, so the sum of the oxidation numbers must equal zero.
What is the oxidation number of Ag and Cl in AgClO4?
The oxidation number of Ag in AgClO4 is +1, as it is a common oxidation state for silver in compounds. The oxidation number of Cl in AgClO4 is +7, as it is in the ClO4- ion which has a total charge of -1.
What is the oxidation number of Ag metal?
Zero The oxidation number of an element in its elemental form is always zero.
