Hydrogen Iodide Color
On the color of hydrogen iodide
There is a name for hydrogen iodide in the world, and its color change is quite wonderful. Under the normal state of hydrogen iodide, it is colorless and stimulating. When encountering other things, or in a foreign place, the color change is obvious.
If in light or heat, hydrogen iodide gradually divides, hydrogen escapes and iodine comes out. Iodine is purple-black in nature, so the color of hydrogen iodide is gradually dyed with purple. At first it is slight, if the mist is light; then it gradually thickens, like the beginning of a purple cloud. This change is due to the liveliness of hydrogen iodide, and when it encounters the cause that can promote its decomposition, there is a wonder of this color change.
If placed in a closed device, the internal air pressure, temperature, etc. change slightly, the color of hydrogen iodide will also change. When the pressure increases and the temperature drops, the polymerization of hydrogen iodide is prosperous, and the color repetition tends to be light and almost colorless. On the contrary, when the pressure decreases and the temperature rises, the decomposition intensifies, and the purple meaning deepens.
Looking at the color change of hydrogen iodide, it can be seen that the physical properties change with the environment. Everything in the world is not isolated and unchanged. Under the influence of interaction and environment, the color change is endless. In the meantime, people can observe the microscopic and understand, and explore physics, in order to obtain the wonders of nature.
