Noun:

সেলেনিউম্,

selenous's Usage Examples:

It dissolves in water to form selenous acid, H2SeO3.

the hydrogenselenite ion, HSeO− 3, is formed; in more acidic conditions selenous acid, H2SeO3, exists.

It is composed of a mixture of selenous acid and concentrated sulfuric acid, which is dripped onto the substance.

considered an acidic oxide: it dissolves in water to form selenous acid.

Often the terms selenous acid and selenium dioxide are used interchangeably.

Instead, selenic acid may also be prepared by the oxidation of selenous acid (H 2SeO 3) with halogens, such as chlorine or bromine, or with potassium.

In contrast to the analogous compound selenous acid, tellurous acid is only metastable.

solutions that operate in this manner will typically be labeled as containing selenous acid or selenium dioxide.

by oxidation of selenium, first with nitric acid, producing selenous acid.

The selenous acid is neutralized to form sodium selenite.

SeO3 + 2 KOH → K2SeO4 + H2O Alternatively, it can be made by reacting selenous acid with potassium hydroxide, and then oxidizing the resulting potassium.

from copper(II) acetate and selenous acid.

36 V and selenous acid is +0.

chloroform and ethyl bromide, but decomposes in water, so that it produces selenous acid in wet air.

SbPh3 → SeCl2 + Cl2SbPh3 Selenium tetrachloride reacts with water to give selenous and hydrochloric acids:[page needed] SeCl4 + 3 H2O → H2SeO3 + 4 HCl Upon.

hydration-dehydration and tautomeric equilibria involving 1,3,5- and 1,2,4-triazines, selenous acid and mytomicin C, reactions of bile acids, cholesterol, and other sterols.

This reaction allows the separation of tellurium from selenium since selenous acid remains soluble at low pH.
