o22.The addition of any acid to the nitrate solution is equivalent to nitric acid, so it has strong oxidizing properties.
The thermal decomposition of nitrate.
1) Nitrate is easy to decompose and release oxygen when heated.
Oxygenated acids are unstable, and their corresponding salts are also prone to decomposition when heated.
At high temperatures, nitrates are strong oxidants: oxygen is produced when they decompose.
2) Thermal decomposition of nitrate:
The salts corresponding to K to mg in the table of metal activity sequences are thermally decomposed to form nitrite and oxygen.
ca(no3)2=
ca(no2)2+o2↑
b Metal oxides, NO2 and O2 are formed when the salts corresponding to mg to cu in the table of metal activity are heated by heat
2cu(no3)2
2cuo+4no2↑+o2↑
Note: There is no gas left in the water after the product of this type of salt is heated: NO2+O2+H2O=2HNO3
The salts corresponding to the metals after Cu in the table of metal activity sequences are heated to form metal elementals, No2 and O2

By the way, nitrite is carcinogenic, and there are some in kimchi, and ingesting a small amount of nitrite nitrite will be metabolized in a very short time, so that.
If you eat too much, you will get sick.

Anonymous users2024-02-05Concentrated nitric acid is unstable and will decompose when exposed to light or heat, releasing nitrogen dioxide.
The nitrogen dioxide produced by decomposition dissolves in nitric acid, giving it a light yellow appearance. However, dilute nitric acid is relatively stable.
Nitric acid can be esterified with alcohols.
In terms of mechanism, the esterification reaction involved in nitric acid was thought to form carbocation intermediates in the past, but many literatures describe the mechanism as Fischer esterification, that is, "acid dehydroxyl alcohol dehydrogenation" and carboxylic acids.

Anonymous users2024-02-04The nitrate chemical formula is nano3, kno3, cu(no3)2, agno3, ca(no3)2, fe(no3)2, fe(no3)3;In addition, nitrate is a salt that contains nitrate.
Nitrate is the earliest general term for nitric acid-derived compounds, which are generally salts composed of metal ions or ammonium ions and nitrate ions; Moreover, nitrate is an ionic compound, containing nitrate ion NO3- and corresponding positive ions, such as NH4+ ions in ammonium nitrate. Pure merger.
Because nitrite has preservative properties and can be combined with myoglobin in meat to be more stable, it is often added in the food processing industry as a color retention agent in sausages and bacon to maintain a good appearance; Secondly, it can prevent the production of Clostridium botulinum and improve the safety of meat products. >>>More
