What are the uses of salt and what are the functions of salt

The use of salt on the first floor is very detailed, I will not repeat it, I only add you to the question.

Salts are compounds that can generate metal ions and acid ions when ionized, and they are also mineral salts. When ionized, salt that can produce iodine and acid ions are called "iodized salts", and they all contain iodine. The iodized table salt we eat is sodium chloride, NaCl, and iodized salt.

The coarse salt is sodium chloride NaCl and some impurities, such as potassium nitrate KN03. Therefore, large crystals are also called large-grain salts, and when purified, the crystals become smaller and become fine salts.

Sea salts are soluble salts, and the main component is sodium chloride NaCl, and there are many other salts (too many to give examples).

Salt can be used to prepare chlorine, hydrogen, hydrochloric acid, sodium hydroxide, chlorate, hypochlorite, bleaching powder and sodium metal, etc., and is an important chemical raw material. Salt can be used for food flavoring, curing meats, salting out soaps, tanning leather, etc. Highly refined salt can be used to make normal salt water.

1. Salt can be used to prepare chlorine, hydrogen, hydrochloric acid, sodium hydroxide, chlorate, hypochlorite, bleaching powder and sodium metal, etc., which is an important chemical raw material.

2. Salt can be used for food seasoning, curing meat, salting soap, tanning leather, etc.

3. Highly refined salt can be used to make normal salt water.

The process of edible salt production is generally divided into four major processes: tide collection, halogen making, crystallization, and salt collection.

Seawater is the raw material for the production of salt, and in order to ensure the normal progress of production, we must do everything possible to ensure the quality of the raw materials. At present, there are two ways to absorb the tide:

First, the tide. (1) The first is natural tide acceptance, which is to let the sea water flow naturally along the tidal diversion ditch at high tide;

2) The second is the power of the tide: the power of the tide generally uses axial flow pumps to introduce seawater, which is characterized by not being limited by natural conditions.

Second, halogen. Brine production is carried out in a vast evaporation pond, and the water depth of the evaporation pond is properly grasped according to the daily evaporation amount, so that the brine concentration is gradually increased, and finally concentrated into saturated brine.

3. Crystallization. (1) In the process of continuous evaporation and concentration of seawater, the concentration of various salts continues to increase: when the salt concentration reaches saturation, it will be precipitated in the form of crystals

2) In a supersaturated solution, the supersaturation of the solution is continuously maintained, and the crystals can continue to grow.

Fourth, collect salt. Finally, the grown salt is put away manually or mechanically.

The benefits of edible salt are as follows:

1. Salt is the main sodium and chlorine required by the human body, which can not only maintain the osmotic pressure of extracellular fluid, but also regulate the balanced distribution of water in the human body.

2. It can also participate in the production of gastric acid, promote the secretion of digestive juices, and increase appetite.

3. It can clear fire, cool blood, nourish kidneys, and strengthen teeth.

4. Heat stroke in hot summer, excessive sweating and polydipsia, sore throat, oral inflammation, bleeding gums, and lack of stomach acidSymptoms such as indigestion, dry stools, and habitual constipation: an appropriate increase in salt intake can be relieved.
