Sodium nitrate does not refer to salt, sodium chloride is. Sodium nitrate is a kind of inorganic salt, the chemical formula is nano3, white solid powder, also known as Chilean saltpeter or Peruvian saltpeter (less common) Its aqueous solution is neutral, PH is about. The world's largest sodium nitrate mine is located in the Atacama Desert in Chile.
Chemical properties of sodium nitrate:
Sodium nitrate is oxidizing and can react with lead to produce sodium nitrite and lead oxide. Hydroiodic acid is also oxidized to iodine element at room temperature to form nitric oxide, the equation is: 2nano3 + 8hi = 2nai + 3i2 + 2no 4h2o.
Sodium nitrate and sodium oxide are heated at 700°C in a silver crucible for about 7 days to produce white crystalline sodium nitrate (Na3NO4), which is very sensitive to water vapor and carbon dioxide.

Sodium nitrate is an inorganic salt, a white solid powder also known as Chilean saltpeter or Peruvian saltpeter. It can be synthesized by the following chemical formula: NaOH (AQ) + HNO3 (AQ) nano3 (AQ) + H2O(1) Sodium nitrate is heated to 380 to decompose to produce sodium nitrite and oxygen.
It reacts with lead to produce sodium nitrite and lead oxide, and hydroiodic acid is also oxidized to elemental iodine at room temperature to form nitric oxide.
The role of sodium nitrate.
1. In the enamel industry, it can be used as flux, oxidant and raw material for the preparation of tantalum powder.
2. In the glass industry, it can be used as a decolorizing agent, defoamer, clarifier and oxidant for various glass and products, etc.
3. In the food industry, it can be used as a colorant for meat processing to prevent meat from deteriorating and impart a seasoning effect.
4. In the fertilizer industry, it can be used as a fast-acting fertilizer for acidic soils, especially root crops such as sugar beet and radish.

Sodium nitrate, is an inorganic substance with the chemical formula nano3. Its chemical properties are that it decomposes when heated to 380. It is very soluble in water and liquid ammonia, soluble in methanol and ethanol, very slightly soluble in acetone, and slightly soluble in glycerol.
When dissolved in water, it absorbs heat, the solution becomes cold, and the aqueous solution is neutral. It is obtained by absorbing nitrogen oxides from alkaline solution used in industrial production, and then evaporating and crystallizing.
Sodium nitrate is a raw material for the manufacture of potassium nitrate, picric acid, dyes, etc. A nitrifying agent for the manufacture of dye intermediates. The glass industry is used as a defoamer, decolorizing agent, clarifier and oxidation flux for the production of various glass and its products.
The enamel industry is used as an oxidizing agent and flux for the preparation of enamel powder. It is used as a metal cleaning agent in the machinery industry and is also used in the preparation of ferrous metal bluening agent. The metallurgical industry uses several dry as a heat treatment agent for steelmaking and aluminum alloys. An accelerant used in the light industry to make cigarettes.
It is used as a medium for penicillin in the pharmaceutical industry. The fertilizer industry is used as a fast-acting fertilizer for the next crop in acidic soils, especially for root crops such as sugar beets and turnips. It is also used as a decolorizing agent for molten caustic soda.
Sorghum has less stringent soil requirements and has the ability to adapt to a variety of soils. It is more resistant to barrenness and salinity. When the soil salt content is less, the growth is normal; inhibited; When exceeded, no seedlings will emerge, or die. >>>More
A closure is when another function is defined inside a function, and the inner function is returned as a function object, while also storing the state information of the outer function. This inner function can depend on the variables and parameters of the outer function, and the outer function returns a reference to the inner function. This way of defining a function inside a function and returning it is called a closure. >>>More
As far as our sun is concerned, it may become a black hole after death, depending on its mass, a black hole is the final stage of stellar evolution, the star will shrink after its own fuel thermonuclear reaction is exhausted, the massive one may carry out a supernova explosion to reduce its mass to slow down its contraction into a white dwarf star or neutron star, if the mass is superlarge, it will further collapse from the neutron star into a black hole, a black hole is a celestial body with a large mass and ultra-small volume, it is not a "hole" in the literal sense, it is a celestial body, Because its gravitational pull is so great that light cannot escape within its Schwarzschild radius, it appears from a telescope as a "black hole" with a radius of Schwarzschild radius", the black hole will evolve again and eventually become a singularity, which is where the universe was born To add that in fact, black holes are generally not easily observed by telescopes, and it is found that it depends on the trajectory of nearby celestial bodies.
