⚗️ Chemical & Physical Properties
Selenic acid is a colorless and odorless, highly corrosive liquid. It is classified as a strong acid due to its ability to completely ionize in solution.
With a molar mass of 128.97 g/mol and a density of approximately 2.599 g/cm³, selenic acid is heavier than many common household items. For comparison, water has a molar mass of 18.02 g/mol and a density of 1 g/cm³.
Selenic acid has a melting point of 58.5 °C and a boiling point of 221 °C. These values are significantly higher than those of many common household items, which typically have lower melting and boiling points.
Selenic acid is highly soluble in water and is known for its high viscosity. In comparison to common household items, such as salt and sugar, selenic acid exhibits superior solubility in water and higher viscosity due to its strong acidic nature.
🏭 Production & Procurement
Selenic acid, a chemical compound with the formula H2SeO4, is typically produced through the oxidation of selenium dioxide, a byproduct of some industrial processes involving selenium compounds. The oxidation process can be carried out using various methods, including the reaction of selenium dioxide with hydrogen peroxide or via electrolysis.
Once produced, Selenic acid can be procured through chemical suppliers who specialize in inorganic chemicals. The compound is typically available in liquid form at various concentrations, depending on the intended application. Selenic acid is considered a hazardous substance and should be handled with care, following strict safety guidelines.
Transportation of Selenic acid is subject to regulations governing the shipment of hazardous materials. Proper labeling and packaging are required to ensure safe transportation.
