Ammonia is a commonly used chemical agent that is alkaline and corrosive, and is commonly used for cleaning, disinfection, and decontamination. In laboratories and industrial production, it is often necessary to use different concentrations of ammonia. Of these, ammonia at 10 is a common concentration that can be configured with the following steps:
1.Prepare the ammonia water configuration container.
Choose a suitable container, such as a beaker, volumetric flask, etc., and coat the inner wall of the container with a layer of petroleum jelly to prevent ammonia volatilization and contamination.
2.Weigh the ammonia.
Weigh 10 grams of ammonia using an electronic balance and pour it into a dispensing container.
3.Add water.
Add enough water until the total volume of ammonia and water in the container reaches the volume of the configured container.
4.Stir.
Using a tool such as a glass rod or agitator, mix the water and ammonia well and stir well until the concentration of ammonia is evenly distributed in the water.
5.Check the concentration.
Using a concentration meter or other concentration measuring instrument, check that the concentration of ammonia is 10. If the concentration is insufficient or exceeds 10, the above steps can be repeated until the desired concentration is reached.
It is important to note that ammonia is a volatile chemical, so it is necessary to pay attention to safety when dispensing ammonia to avoid hazards such as ammonia poisoning and fire. At the same time, when dispensing ammonia, laboratory equipment and personal protective equipment that meet the requirements should be used, and laboratory safety norms and operating procedures should be strictly adhered to.
