Read： 436 Time：13months ago Source：Transform the World with Simplicity

In chemical experiments, ammonia ammonium chloride buffer solution is a commonly used buffer, which can stabilize the pH value of the solution and make the experimental results more accurate and reliable. However, in the use of ammonia ammonium chloride buffer solution, also need to pay attention to some matters, so as not to cause experimental failure or safety problems. The following is the correct use of ammonia ammonium chloride buffer solution. Before

using ammonia ammonium chloride buffer solution, it is necessary to ensure the quality of the solution and avoid using expired or contaminated solution. At the same time, we should also pay attention to the storage conditions, avoid direct sunlight or high temperature environment, so as not to affect the stability of the solution. When the

uses the ammonia ammonium chloride buffer solution, it is necessary to prepare the solution strictly according to the preparation ratio to avoid the deviation of the experimental results due to the inaccurate concentration of the solution. In the preparation process, it is also necessary to pay attention to mixing evenly to ensure that the various ingredients are fully mixed. When

use ammonia ammonium chloride buffer solution for experiments, it is necessary to read the experimental method carefully to ensure that the buffer solution used meets the experimental requirements. At the same time, we should also pay attention to the operation specification in the process of the experiment, so as to avoid the failure of the experiment or the safety accident caused by the operation error. After the

uses the ammonia and ammonium chloride buffer solution, it is necessary to clean the experimental table and experimental utensils in time to avoid residues affecting the accuracy of the next experiment. At the same time, we should also pay attention to the treatment of waste liquid to avoid pollution to the environment.

the above points, the correct use of ammonia and ammonium chloride buffer solution needs to pay attention to the quality of the solution, the proportion of preparation, experimental requirements, operating specifications and the cleaning work after the experiment. Only in strict accordance with the requirements of the operation, in order to make the experiment more accurate and reliable, so as to obtain the experimental results in line with the requirements of scientific research.
