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.
What is the use of nesslers reagent?
Nessler's reagent is primarily used for the qualitative and quantitative determination of ammonia and ammonium ions in various samples, such as water or soil. When ammonia reacts with Nessler's reagent, it produces a colored complex, typically ranging from yellow to brown, which can be measured spectrophotometrically. This reaction allows for the assessment of nitrogen levels in environmental testing and water quality analysis. Additionally, it helps in evaluating the effectiveness of wastewater treatment processes.
What is thee purpose of adding methylene blue to the specimen?
Adding methylene blue to a slide will stain animal cells and make the nuclei more visible.
What is a reagent strip?
The reagent strip is a strip of paper impregnated with a specific chemical reagent for a chemical determination.
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.

What is the chemical formula for Heisenberg reagent?
The chemical formula for Heisenberg reagent varies depending on the specific reaction or purpose it is being used for. It is not a standard chemical compound with a fixed formula.

Why is it unwise to put AR calcium carbonate back in the bottle after an experiment?
The purpose is to avoid any contamination of the reagent in the bottle.

What is aluminon reagent?
Aluminon is not a reagent. Aluminum is a metallic element.
What is composition of KF reagent?
What is the chemical composition of kf reagent
What is the opposite of a limiting 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.
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.
What exactly is a reagent in English?
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.)
