You may not have heard of activated alumina. But probably you and your family have used active alumina many times. It may even be used in the water filters under your sink. This material is a form of alumina that has porosity and a high absorption surface for liquids and gases. Alumina, a chemical compound consisting of aluminum and oxygen molecules (Al2O3), is a white or brown crystalline material and is found in many Industries are used. This substance is found in nature as mineral corundum. The image below is a view of mineral corundum.

### sodium hydrosulfite\r\nCombined sodium hydrosulfite with the chemical formula Na2S2O4 has other names including sodium dithionite and the brand name Hydro. It is a white to light yellow crystalline solid and has a smell similar to sulfur dioxide. Hydro heats up by itself in contact with air and moisture. This heat may be enough to ignite the substance. Therefore, avoid exposing this material to fire or extreme heat for a long time. The molecular structure of this substance is given in the picture below.\r\n### Hydro use in industry\r\nSince sodium dithionite is soluble in water, it is used ...

### What is nitric acid?\r\nNitric acid (HNO3) is a very corrosive mineral acid. This pure compound is colorless and turns yellow over time due to decomposition into nitrogen oxides and water. Most of the nitric acid available in the market has a concentration of about 68% by mass. When the concentration of HNO3 solution is more than 86%, it is called sooting nitric acid. Depending on the amount of nitric acid present in the aqueous solution of this substance, in concentrations of about 86% it is red sooting nitric acid and in concentrations above 95% it is white sooting nitric acid.\r\n\r\nNi ...

What is phosphoric acid?\r\nHave you ever looked at the ingredients list of your favorite soft drink? Most likely, you will see phosphoric acid. This substance is one of the common additives in many processed foods that manufacturers use to flavor and preserve food freshness.\r\n\r\nPhosphoric acid is a colorless and odorless mineral acid containing phosphorus. This substance is a separating agent that binds to many divalent cations including Fe2+, Cu2+, Ca2+ and Mg2+. This substance is used in dentistry and orthodontics as an etching solution to clean the dental surfaces where dental devices ...

The main applications of phosphoric acid include the production of phosphates and phosphate-based fertilizers, soaps and detergents, acidification and preservation of food, soft drinks, water treatment, and toothpaste. Some other specific applications of phosphoric acid include anti-rust treatment with phosphate coating, phosphoric acid fuel cells, activated carbon production, compound semiconductors, microfabrication for silicon nitride etching, pH adjuster in skin care products, and disinfectants in the dairy industry. . Phosphoric acid also has other metallurgical functions such as cleaning ...

### 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, inclu ...

### What is sodium acetate?\r\nSodium acetate (CH3COONa), often abbreviated NaOAc and also sodium ethanoate, is the sodium salt of acetic acid. This salt, which is also slightly alkaline, appears as a colorless diluting salt with a wide range of uses.\r\nThis colorless salt has a wide range of uses. Among its uses, it can be used in the textile industry to neutralize sulfuric acid waste. In the production of synthetic rubber, sodium acetate is used to prevent high heat. In the production of cotton (linen) clothes, sodium acetate is used to prevent the accumulation of static electricity. This s ...

### Garnet\r\nGarnet is a name that refers to a large group of rock-forming minerals. These minerals have a common crystal structure and general chemical composition X3Y2 (SiO4)3. In this general structure, X\" can be Ca, Mg, Fe2+ or Mn2+\" and Y\" can be Al, Fe3+, Mn3+, V3+ or Cr3+\".\r\n\r\nThese minerals are found all over the world in metamorphic, igneous and sedimentary rocks. Most near-surface garnets form when a sedimentary rock with a high aluminum content, such as shale, is subjected to enough pressure and heat to produce schist or gneiss. Garnet is also found in contact metamorphic r ...
