On the hygroscopicity of ammonium acetate
The physical properties of the world vary. Ammonium acetate has the characteristics of hygroscopicity. Looking at it in the room, if it is filled with moisture, it is like a sponge absorbing water, quietly absorbing the surrounding water vapor.
This hygroscopicity comes from the characteristics of its molecular structure. Ammonium acetate particles attract each other with water molecules. Just like magnets attract iron, water molecules are attracted by ammonium acetate and gradually attach to its surface, gather and increase, resulting in a gradual change in its shape. At first or only slightly moist, after a long time, droplets appear, as if water seeps from the inside out.
In all kinds of scenes, this characteristic is obvious. If stored in an unsealed vessel, it can be seen that the surface is moist and moist after a long time. In chemical preparation, if its hygroscopicity is not observed, or the purity of the raw materials is changed, the quality of the product will be affected. In the field of scientific research, accurate experiments need to control the environmental humidity, ammonium acetate moisture absorption, or disturb the accuracy of the experiment, so that the results are deviated.
Therefore, to recognize the hygroscopicity of ammonium acetate, when used, it should be strictly sealed and sealed to avoid moisture, so as to ensure its purity and correct use. Everything goes smoothly, so as not to cause many mistakes due to moisture absorption.
