40g urea+ 80ml of 40%H2SO4! add 2g stannous chloride, heat untill solution is clear and make the volume upto 100ml. it is called foulger's reagent!

Formaldehyde Schiff's reagent: It is a solution of formaldehyde and sulfuric acid, used to detect the presence of aldehydes. The equation involves the formation of a colored compound with aldehydes. Benzaldehyde Schiff's reagent: Benzaldehyde can act as a Schiff's base with primary amines to form imines. The reaction results in the formation of a colored compound. Acetone Schiff's reagent: Acetone can react with a primary amine to form a Schiff's base, leading to the formation of a colored compound.
Use a graduated pipette or syringe to measure and transfer 5ml of liquid reagent from the large reagent bottle. Make sure to carefully handle and dispense the reagent to avoid spills and contamination.
Tollen's reagent is a test used to detect the presence of aldehydes, as it produces a silver mirror when it reacts with aldehydes, but not with ketones or other compounds. Baeyer's reagent is a solution of potassium permanganate (KMnO4) used to oxidize and distinguish between primary and secondary alcohols. Primary alcohols are oxidized by Baeyer's reagent to form carboxylic acids, while secondary alcohols are oxidized to form ketones.
Foulgers test is a chemical test used to detect the presence of carbohydrates. It involves heating the carbohydrate sample with hydrochloric acid to break down the carbohydrates into simple sugars, which are then detected using a colorimetric reagent like Fehling's solution or Benedict's solution. A color change to brick-red or yellow precipitate indicates a positive result for the presence of carbohydrates.
The reagent strip is a strip of paper impregnated with a specific chemical reagent for a chemical determination.
Biuret reagent is used to test for protein in urine. It is a common test that students in biology class perform. Urine is added to a test tube, followed by approximately the same amount of Biuret reagent. If the solution turns lavender this means that there are proteins present in the urine.
Aluminon is not a reagent. Aluminum is a metallic element.
What is the chemical composition of kf reagent
The opposite of a limiting reagent is an excess reagent. While a limiting reagent is the reactant that is completely consumed first in a chemical reaction, thereby determining the maximum amount of product that can be formed, the excess reagent is present in a greater quantity than needed to fully react with the limiting reagent. As a result, some of the excess reagent remains unreacted after the reaction is complete.
The LAL reagent water can be sterile WFI or other water that show reaction with the specific LAL reagent with which it can be used, at the limit of the sensitivity of such reagent.
A reagent is a chemical substance that reacts with some other substance. It is common to add a specific reagent to an unknown substance to determine whether or not the substance that the particular reagent reacts to is present. (For example, add a reagent for sugar to test for the presence of sugar.)
biuret reagent
Biuret reagent detect peptide bonds.
NH4+ is detected by nessler's reagent.
This reagent is bromine in solution.
