What is the composition of household salt? Also, why are snakes afraid of sulfur?

Salt sodium chloride Na Cl I (K) O sodium iodate or potassium iodate is often added to salt. (Iodized salt) At present, there is 1 edible salt in the market, and the main components are sodium chloride and potassium iodate. 2. Calcium fortified nutrients, using common iodized salt as carrier and adding a certain amount of active calcium. 3. Zinc fortified nutrient, using common iodized salt as carrier and adding a certain amount of zinc lactate. 4. Selenium fortified nutrients, using common iodized salt as carrier and adding a certain amount of sodium selenite. There are also iron fortified nutrients, low sodium salt, salt and so on. It should be realgar and sulfur. Not only are snakes afraid, but the taste is unbearable! Realgar is a stomach medicine, and snakes are very sensitive to it. However, the realgar added with alcohol is farther away and has better snake repellent effect, because alcohol can be used as a "diluent" to enhance the volatilization of realgar. So! In mountainous areas, realgar is usually soaked in wine, and it is also photographed in the legend of the new White Snake. However, it is not completely harmful. On the other hand, I can also say that "three poisons eat poison separately". Realgar and cinnabar are often used together to treat diseases, saving many lives. Let's talk about the composition of "realgar" and the corresponding "orpiment". Do you have orpiment? Am I talking nonsense? No, actually, these are two different mineral compositions! 1, realgar is also called stone yellow, smoked yellow, etc. The mineral name is also called realgar, and the chemical composition is arsenic sulfide A s S S orange, which is crisp and smelly. It is a folk medicine with a long history of detoxification, sore treatment and insecticide. For thousands of years, people in China have had the habit of drinking realgar wine during the Dragon Boat Festival and the coming summer, that is, using realgar to detoxify and kill insects. Realgar will become As2O3 after oxidation, which is the famous arsenic, another famous mineral medicine, which is very toxic, and its detoxification and insecticidal principle is also here. 2. orpiment is also called Kunlun Yellow and Arsenic Yellow, and the mineral name also follows orpiment name, and its composition is As 2S3. Its color is lighter than realgar, and it is brittle. Orpiment and realgar often coexist, and their properties are similar to those of realgar, which is often used as the main drug for detoxification and insecticidal. Oxidation will also turn into arsenic. Also known as "yellow" is sulfur, also known as sulfur, leaving yellow and so on. The mineral name is natural sulfur. Pale yellow, very brittle, low ignition point, and turns into SO2 after burning, giving off an unpleasant smell. Its taste is sour and warm, it can warm the intestines, relieve constipation, kill insects and relieve itching, and it can also replenish fire and help yang. When sulfur comes into contact with skin secretions, it can form alkali sulfide, which has the functions of softening epidermis and killing parasites. The curative effect of sulfur external use should be related to this. Well, there are many sensitive words, and some places can only be passed by spaces. You can read them together, that's all! Friends, happy Dragon Boat Festival! !
