### What is barium nitrate?\r\nBarium nitrate is an inorganic compound with the chemical formula Ba(NO3)2. It is a white, crystalline powder and, like most barium salts, is colorless, toxic, and soluble in water. It burns with a green flame and is oxidizing.\r\n\r\nBarium nitrate is commonly used in making fireworks.\r\n\r\nIn fireworks, it is primarily used as an oxidizer to provide oxygen for the combustion of other pyrotechnics. When heated, barium nitrate decomposes to release oxygen, which reacts with other materials in the pyrotechnic composition to produce a wide range of effects, including bright colors, sparks, and flames.\r\n\r\nBarium nitrate is often used in combination with other chemicals such as strontium or copper to create certain colors in fireworks. For example, combining barium nitrate with strontium carbonate can produce a bright red color, while combining it with copper oxide can produce a green color.\r\n\r\n### Dangers and safety tips\r\nBarium nitrate is toxic. Inhalation may cause respiratory irritation. While skin or eye contact is less harmful than ingestion or inhalation, it can still result in irritation, itching, redness, and pain.\r\n\r\nA dust mask should always be worn when handling it. A mixture of metal powders and barium nitrate sometimes spontaneously heats up and can catch fire, especially when wet. This can usually be avoided by adding small amounts of boric acid (1-2%).\r\n\r\nBarium nitrate should be stored in closed bottles and away from moisture and flammable materials as well as acid vapors. A glass or plastic bottle with a cap is good enough.

Chlorofric material or iron chloride is in the form of a brown liquid, which is caused by the iron in chlorofric.\r\nLike other water purification materials, iron chloride plays the role of coagulation in purification and the role of separating waste materials and removing unpleasant odors, controlling water color, coagulation of water in order to make it heavier and remove excess materials, dephosphorization and improving the sludge process. Iron chloride 3 is not inflammable in any way.\r\nThe percentage of purity of chloroform varies from 38 to 45%.\r\nIn the water treatment industry, chloroform is produced in liquid and solid form, which is much more and more economical to use and consume the liquid grade.\r\nRegarding the smell of liquid chlorophric, it can be said that it has a pungent and acidic smell.\r\nFor more information, contact the company numbers:

Copper nitrate is an inorganic chemical compound with uniform blue crystals; Dry copper nitrate (without water of crystallization) is blue-green crystals that sublimate at a temperature between 150 and 200 degrees Celsius and under vacuum conditions. Copper nitrate can usually be produced in 5 types with different water of crystallization, but the most common ones are three-water and six-water with the formula Cu(NO3)2 * 2 H2O, and this number of water of crystallization is more commercially and industrially produced than in the laboratory. .\r\n\r\nCopper nitrate is usually obtained from the reaction of copper metal with sulfuric and nitric acid. Copper nitrate has many uses, including the production of copper oxide, as a catalyst in the production of organic substances, the production of pregnancy test strips, and the production of fungicides. Herbicides and bactericides, use in nickel plating bath, production of ceramic paint, use in electroplating and production and dyeing of textiles.
