Preparation of ammonia water
Those who want to do good things in ancient times, make plans and then move. If you want to make ammonia water, you need to understand the reason and be careful about the method.
The first thing to do is to carefully review the materials used. For ammonia gas, it is essential to make ammonia water. The method of obtaining ammonia gas, or co-heating by ammonium salt and alkali. For ammonium salts, such as ammonium chloride, the alkali is calcium hydroxide, and the two are mixed in a kettle. It is burned with fire. The ammonium salt and the alkali are combined, and the ammonia gas comes out. However, this gas has a stinging odor and is lighter than the air. When it is collected, the method of draining the air downward must make the gas pure and free of impurities.
Water is also indispensable for the production of ammonia water. It is necessary to choose clear and free water to maintain the quality of the prepared ammonia water.
Then proceed with the preparation. The collected ammonia gas is slowly introduced into the water. This process must be done with caution, because ammonia is very soluble in water. If introduced too quickly, the water is easy to inhale, resulting in failure. When guiding the gas, the change of the water can be observed. When the water no longer absorbs ammonia, the ammonia water is coarse.
After refining, it should not be ignored. The initial ammonia water may contain miscellaneous gas, or the concentration is not suitable. It can be removed by distillation to adjust its concentration. During distillation, control its heat and observe the changes in its gas and liquid to ensure that the ammonia water reaches the usable level.
The way to make ammonia water is not unique, but also careful at every step, so that good quality ammonia can be obtained for all needs.
