How can you prepare borsches reagent in the lab?
To prepare Borsches reagent in the lab, mix equal volumes of concentrated sulfuric acid and glacial acetic acid in a fume hood. Then, slowly add 9 parts of water to the mixture while stirring constantly. Allow the reagent to cool before use.
In etards rxn benzaldehyde is prepared by oxidation of toluene by what?
In the Etard reaction, benzaldehyde is prepared by the oxidation of toluene using chromyl chloride (CrO2Cl2). This reagent is a strong oxidizing agent that can efficiently convert the methyl group of toluene into an aldehyde group, yielding benzaldehyde as the final product.
How do you prepare Schultz Reagent?
To prepare Schultz reagent, mix one part of concentrated sulfuric acid with nine parts distilled water. Allow the mixture to cool before use. This reagent is commonly used for the detection of proteins in biological samples.
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 procedure to prepare anthrone reagent?
To prepare anthrone reagent, dissolve 200 mg of anthrone in 100 ml of concentrated sulfuric acid. Mix the solution thoroughly and allow it to cool before use. Anthrone reagent is used for the detection of carbohydrates, specifically sugars, in various biological samples.
How prepare benzen hexa clorief from benzen?
The Benzene hexa clorief is prepared by light-induced addition of chlorine to benzene.
What are the two most important reagent for the conversion of nitro toluene to toluene?
From what the internet shows, you convert toluene into nitro-toluene, not the other way around. Further, the reagents used to do that are generally things that will allow the toluene to oxidize.

How do you prepare tollen reagent?
To prepare Tollens reagent, mix aqueous silver nitrate with ammonia solution until a precipitate forms. Then add sodium hydroxide solution to redissolve the precipitate and form the final reagent. It is used to test for the presence of aldehydes in a reaction.
How do you prepare nesslers reagent?
To prepare Nessler's reagent, dissolve 7g of mercuric iodide and 35g of potassium iodide in distilled water, and then add 100g of potassium hydroxide pellets. Once the solution is clear, dilute it with water to make 1 liter of Nessler's reagent. This reagent is commonly used for detecting ammonia in solutions.
How do you prepare seliwanoffs reagent?
To prepare Seliwanoff's reagent, dissolve resorcinol in concentrated hydrochloric acid, then add a small amount of acetaldehyde. Mix well and dilute with water if needed. This reagent is used for differentiating between aldose and ketose sugars based on the color developed upon heating.
How do you prepare kedd's reagent?
To prepare Kedde's reagent, mix equal volumes of concentrated hydrochloric acid and 5% potassium dichromate solution. The reagent is used to test for the presence of fatty acids in a substance, where a positive test results in the formation of a layer of orange crystals.
