selenic acid
Noun 1. A strong acid (H₂SeO₄) analogous to sulfuric acid: A highly corrosive, crystalline acid containing selenium in its highest oxidation state (+6). It is a powerful oxidizing agent and is structurally and chemically similar to sulfuric acid (H₂SO₄), with selenium replacing sulfur.
Selenic acid is primarily discussed in scientific contexts, particularly chemistry and materials science. It is used to describe the specific chemical compound itself, its properties, or its role in reactions. * Selenic acid is a strong oxidizing agent used in some laboratory syntheses. * The chemist handled the selenic acid with extreme caution due to its corrosive nature. * The reaction produced selenic acid as a byproduct.
- Chemical Synthesis and Etching: Selenic acid is used in specific chemical processes, such as the oxidation of certain organic compounds or in the etching of metals.
- Selenic acid can be employed to oxidize ketones to lactones.
- Comparative Chemistry: The term is often used to highlight similarities and differences within the chalcogen group (Group 16) of the periodic table, comparing it to sulfuric and telluric acids.
- Unlike sulfuric acid, selenic acid is a strong oxidizing agent even when dilute.
- Selenate (n): A salt or ester of selenic acid (e.g., sodium selenate, Na₂SeO₄).
- Selenous Acid (n): The related acid where selenium has an oxidation state of +4 (H₂SeO₃), analogous to sulfurous acid.
- Hydrogen selenate (Systematic IUPAC name)
- Dihydrogen selenate
The term selenic acid refers exclusively to the specific chemical compound H₂SeO₄. It is not used in general language or metaphorically. Its meaning is fixed within the domain of inorganic chemistry.
