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.

Benedicts reagent is used to check reducing sugars , it need hat to work and gives red color when positive ,. While biuret reagent is for proteins .there is no need to use heat and gives purple , violet color when positive ..
The Benedict's reagent is commonly used to detect the presence of glucose in a solution. This reagent changes color from blue to green, yellow, orange, or red, depending on the amount of glucose present.
To find the limiting reagent in a chemical reaction, you calculate the amount of product that each reactant can produce. The reactant that produces the least amount of product is the limiting reagent. You can then use this information to determine the amount of product that can be formed in the reaction.

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.
1)they are use to form laboratory salt when combined with acid. 2)they are used to detect the chemical reagent. 3)they are use to manufacture many laboratory reagent.

The cheaper reagent is usually the reagent that is used in excess. This procedure is purely for economic reasons.
Using a dry and clean spatula helps prevent contamination of the reagent. Spooning out small amounts of solid ensures accurate measurement and avoids waste of reagent. Remember to close the reagent bottle tightly after use to maintain its integrity.
Your question supplies its own answer, though you may need to ensure the bottle's material will withstand the intended reagent.

No, different compounds require different reagents for testing due to their unique chemical properties. Using the wrong reagent may not produce accurate results or could even be dangerous. It is important to use the appropriate reagent for each type of compound being tested.
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.
