The main component of table salt, the main component of table salt

The main component of table salt is sodium chloride, and the sodium chloride content of well salt and mineral salt shall not be less than 95%. Salt has a very long history in our country, and salt has been boiled in the period of Shennong and the Yellow Emperor, and China is the place where salt wells were invented. Table salt has a wide range of functions, mainly used in sterilization and disinfection, dental care, beauty, cleaning, decontamination, medical treatment, food and other aspects.

The main component of table salt is sodium chloride, and the state stipulates that the sodium chloride content of well salt and mineral salt shall not be less than 95%. Table salt contains impurities such as barium salts, chloride, magnesium, lead, arsenic, zinc, sulfate, etc. Sodium chloride is an ionic compound, chemical formula NaCl, colorless cubic crystalline or fine crystalline powder, salty in taste.

The appearance is white crystalline, and its ** is mainly seawater, which is the main component of table salt.

Salt is divided into single salt and combined salt, single salt is divided into normal salt, acid salt, basic salt, and combined salt is divided into double salt and complex salt. Among them, the acid salt contains hydrogen ions in addition to metal ions and acid ions, and the basic salt contains hydroxide ions in addition to metal ions and acid ions. When complex salts are dissolved in water, complex salt complexes of complex ions that are different from the original salts can be generated.

Strong alkali weak salt is a salt that reacts with a strong base and a weak acid, which is alkaline when dissolved in water, such as sodium carbonate. The strong acid and weak alkali salt are the salts that react with strong acids and weak bases, and are acidic when dissolved in water, such as ferric chloride.

First, the main part of table salt.

The main ingredient of table salt is sodium chloride, which accounts for 99% of the salt content, but there are some areas where potassium chloride is added to the salt to reduce the sodium chloride content, so as to prevent high blood pressure.

2. People who are contraindicated to table salt.

Although salt is so important to our lives, there are still some groups of people who are not suitable for salt, such as patients who are coughing and edema, should avoid eating salt-added foods, and can eat some light foods during illness to reduce salt intake.

People with high blood pressure, kidney disease and cardiovascular disease should also stay away from table salt, because salt can aggravate these conditions and even cause very dangerous consequences, and it is best for such people to use salt substitutes (potassium chloride) or unsalted soy sauce instead of daily salt.

The main component of table salt is sodium chloride (NaCl).It also contains magnesium chloride (the main reason why some salts taste astringent) before purificationStill others contain nitrite, a substance that is toxic to humans, and some unscrupulous traders use industrial salt to pass off as table salt to cause food poisoning.

Now we also add potassium iodate to the table salt we eat, which becomes iodized salt.

Hope it helps.

The main component of table salt is sodium chloride.

Edible salt refers to processed edible salt with sodium chloride as the main ingredient obtained from seawater, underground rock (mineral) salt sediments, and natural brine (salt) water, excluding low-sodium salt. The main component of edible salt is sodium chloride (NaCl), which also contains a small amount of water and impurities and other elements such as iron, phosphorus and iodine. Salt is a colorless transparent cubic crystal with a melting point of 801, a boiling point of 1413, and a relative density.

Salt - sodium chloride gives the "taste of China" the basic taste of the taste feast, is a basic component in the human tissue, and plays an important role in ensuring people's normal physiological and biochemical activities.

How to preserve salt

1. Edible salt needs to be stored in a dry and cool place, so as to avoid moisture and deterioration before the salt rots. If you are using a plastic or paper bag to package salt, you can put it in an airtight container to ensure the freshness of the salt.

2. Sunlight will make the salt moist and viscous, so you need to avoid direct sunlight, and it is a good choice to store the salt in a dark place or use an opaque container.

3. Although it is a common practice to mix salt and spices, it is not conducive to the preservation of salt. The oils in spices can cause salt to deteriorate, which can affect its taste and nutritional value.

The main ingredient of table salt is sodium chloride. In addition, table salt may also contain impurities such as barium salts, chloride, magnesium, lead, arsenic, zinc, sulfate, etc.

Edible salt is processed edible salt with base-chain sodium chloride as the main ingredient obtained from seawater, underground rock (mineral) salt sediments, and natural brine (salt) water, excluding low-sodium salt.

1.Salt generally refers to table salt, the main component of which is sodium chloride, and also contains barium salt, chloride, magnesium, lead, arsenic, zinc, sulfate and other impurities.

Salt refers to different sea salt, well salt, mineral salt, lake salt, soil salt and other coarse dust, the state stipulates that the sodium chloride content of well salt and mineral salt shall not be lower than 95%, and the barium content shall not exceed 20mg kg.
