Nessler - Introduction
Nessler is a commonly used reagent, which is mainly used to detect the concentration of ammonium ion (NH4) in aqueous solution. The following is a description of some of the properties, uses, methods and safety information of Nessler:
1. nature:
Nessler is a solution containing mercury ions, usually a deep yellow color. Its chemical formula is (NH4)2HgI4. Nessler has strong reducing and oxidizing properties, and is sensitive to light and air.
2. use:
The Nessler is mainly used for the quantitative determination of ammonium ion concentration in water samples. It can react with the ammonium ion in the solution to generate a brown precipitate, and the concentration of the precipitate is proportional to the concentration of ammonium ion in the original solution, so it can be used to determine the content of ammonium ion in the solution.
3. preparation method:
The common method of preparing Nessler is to dissolve iodinated mercury in a hydrochloric acid solution containing ammonium chloride and potassium iodide, followed by evaporation and concentration.
4. Safety Information:
Nessler contains mercury ions, which are toxic substances. When using the Nessler should pay attention to the following safety matters:
-Avoid direct contact with Nessler as it may cause irritation and damage to the skin and eyes.
-When using the Nessler, ensure that the operation is carried out in a well-ventilated laboratory to prevent the inhalation of toxic gases.
-It is strictly forbidden to contact the Nessler with strong oxidants, because it may cause violent chemical reactions and produce dangerous substances.
-Discarded Nessler must be disposed of correctly in accordance with local regulations.
