Potassium permanganate is widely used in the chemical industry and laboratories as a strong oxidizing agent, and also as a medication for dermatitis, for cleaning wounds, and general disinfection. It is on the World Health Organization's List of Essential Medicines. [5] In 2000, worldwide production was estimated at 30,000 tons. [5]
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
At 15.6 °C (60.1 °F), the density of a saturated solution is 0.88 g/ml; it contains 35.6% ammonia by mass, 308 grams of ammonia per litre of solution, and has a molarity of approximately 18 mol/L. At higher temperatures, the molarity of the saturated solution decreases and the density increases. [ 8 ]
Other grades are UAN 28, UAN 30 and UAN 18. The solutions are quite corrosive towards mild steel (up to 0.5 inches (1.3 cm) per year on C1010 steel) and are therefore generally equipped with a corrosion inhibitor to protect tanks, pipelines, nozzles, etc. Urea–ammonium nitrate solutions should not be combined with calcium ammonium nitrate ...
Hydroxylamine (also known as hydroxyammonia) is an inorganic compound with the chemical formula N H 2 OH.The compound exists as hygroscopic colorless crystals. [4] Hydroxylamine is almost always provided and used as an aqueous solution or more often as one of its salts such as hydroxylammonium sulfate, a water-soluble solid.
The most common regeneration process is the pyrohydrolysis process, applying the following formula: [25] 4 FeCl 2 + 4 H 2 O + O 2 → 8 HCl + 2 Fe 2 O 3. By recuperation of the spent acid, a closed acid loop is established. [7] The iron(III) oxide by-product of the regeneration process is valuable, used in a variety of secondary industries. [25]
Magnesium chloride is an inorganic compound with the formula Mg Cl 2.It forms hydrates MgCl 2 ·nH 2 O, where n can range from 1 to 12. These salts are colorless or white solids that are highly soluble in water.
Sodium methoxide is prepared by treating methanol with sodium: 2 Na + 2 CH 3 OH → 2 CH 3 ONa + H 2. The reaction is so exothermic that ignition is possible. The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation followed by heating to remove residual methanol.
