selenous acid मीनिंग इन हिंदी

उदाहरण वाक्य

1. In many cases of selenium poisoning, selenous acid is formed in the body.
2. Salts of selenous acid are called selenites.
3. Selenous acid is bubbled with sulfur dioxide ( reduction step ) to give elemental selenium.
4. SeO 2 is considered an acidic oxide : it dissolves in water to form selenous acid.
5. Often the terms " selenous acid " and " selenium dioxide " are used interchangeably.
6. Alternatively, it can be made by reacting selenous acid with potassium hydroxide, and then oxidizing the resulting potassium selenite with bromine.
7. Common production from the residue then begins by oxidation with sodium carbonate to produce selenium dioxide, which is mixed with water and acidified to form selenous acid ( oxidation step ).
8. In slightly acid conditions, the "'hydrogenselenite "'ion,, is formed; in more acidic conditions selenous acid, H 2 SeO 3, exists.
9. Na 2 SeO 3 + 2 X + CO 2; the selenide is neutralized by sulfuric acid H 2 SO 4 to give selenous acid H 2 SeO 3; this is reduced by bubbling with SO 2 to yield elemental selenium.
10. Another active area are studies of electroreduction and electrooxidation of some organic compounds, such as aromatic nitrocompounds, various pesticides including maleic hydrazide, 1, 3, 5-and 1, 2, 4-triazines, selenous acid, mitomycin C, phenols, etc . Structure-reactivity relationships are investigated, for example the transfer of electronic effects through an N-N single bond, ring formation of some 2-amino-1, 4-benzoquinones, or interactions between two reducible groups in a molecule.
