What is the molecular formula of schiff reagent?
The molecular formula of Schiff reagent is C20H15N3. It is a chemical reagent used for detecting the presence of aldehydes or ketones in organic compounds.
What is principle of schiffs test?
The Schiff's reagent, which is a mixture of fuchsin-sulfurous acid, is used to detect the presence of aldehydes or compounds with free aldehyde or ketone groups in a sample. When the reagent reacts with the aldehyde group, it forms a magenta-colored complex due to the reduction of the fuchsin dye. This color change is the basis of the Schiff's test, indicating the presence of aldehydes in the sample.
What is a reagent strip?
The reagent strip is a strip of paper impregnated with a specific chemical reagent for a chemical determination.
Why is decolorizing the most crucial step?
It is possible to decolourise gram positive bacteria and thus get false results of all gram negative organisms. Similarly, it is possible to under-decolourise and get all gram positive organisms. Ideally controls of known organisms should be run with each stain.
What chemical reagent of protein?
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.

Equation of formaldehyde schiff's reagent benzaldehyde schiff's reagent and acetone schiff'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.

What is aluminon reagent?
Aluminon is not a reagent. Aluminum is a metallic element.
What is the different between saturated and unsaturated?
Saturated hydrocarbon does not decolourise bromine water while unsaturated hydrocarbon decolourize it.
Is it wfi used for inplace of lal reagent water?
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.
