Sodium selenite is the inorganic compound with the formula Na 2 SeO 3. This salt is a colourless solid. The pink coloured pentahydrate Na 2 SeO 3 (H 2 O) 5 is the most common water-soluble selenium compound.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise.
Sodium selenate is the inorganic compound with the formula Na 2 SeO 4. It exists as the anhydrous salt, the heptahydrate, and the decahydrate. [1] These are white, water-soluble solids. The decahydrate is a common ingredient in multivitamins and livestock feed as a source of selenium. The anhydrous salt is used in the production of some glass.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

ALEX: I had a really hard time forcing myself to go in the room.I wasn’t going to go in. I just wouldn’t do it. My dad said, “If you don’t go in, you will regret it the rest of your life.”
These include silver selenite (Ag 2 SeO 3) and sodium selenite (Na 2 SeO 3). Hydrogen sulfide reacts with aqueous selenous acid to produce selenium disulfide : H 2 SeO 3 + 2 H 2 S SeS 2 + 3 H 2 O {\displaystyle {\ce {H2SeO3 + 2 H2S -> SeS2 + 3 H2O}}}
Over the past four years, the Trump administration has destroyed or distorted vast swaths of information vital to public life and safety. This is an account of the damage.
