selenic

It is the principal oxoacid of selenium; the other being selenic acid.

In very acidic conditions, it makes selenic acid.

It dissolves in water to make selenic acid.

It was another fine moonlit night and the old selenic disc sailed above in a cloudless sky.

It is attacked only by boiling selenic acid which, as you must know, dissolves platinum readily.

Selenates and selenic acid are powerful oxidizing agents.

Selenic acid can even dissolve gold!

Selenic acid is a chemical compound.

Selenic acid is made by oxidation of selenium dioxide with hydrogen peroxide.

Sodium selenate is made by reacting sodium hydroxide with selenic acid.

The selenic acid formed when the silver is reduced is being used in the electrolysis vats as an electrolyte.

It can also be made by dehydrating (removing the water from) selenic acid with a strong dessicant, like phosphorus(V) oxide.

It was the night of the sacrifice to Rhalu, the selenic goddess; and he, Matla, was to play an essential part in the ceremony.

Treatment of selenic acid with fluorosulfuric acid gives the dioxydifluoride (b.p. 8.4 C):

It was not attacked by any acid except boiling selenic acid, since it formed a tremendous number of insoluble salts.

Awesome as always, Aurich Also glad to see so many folks appreciate the glorious selenic selachimorphs as their wallpapers!

It corresponds to the selenic acid, HSeO, which is a strong acid and can in its concentrated form dissolve gold.

Hot, concentrated selenic acid is capable of dissolving gold, forming gold(III) selenate.

Selenoyl fluoride can be formed by the action of warm fluorosulfonic acid on barium selenate or selenic acid.

Another method of preparing selenic acid is by the oxidation of elemental selenium in water suspension by chlorine:

Like sulfuric acid, selenic acid is a strong acid that is hygroscopic and extremely soluble in water.

Selenium trioxide, also known as selenium(VI) oxide and selenic oxide, is a chemical compound.

The HCl and HBr made as a byproduct can reduce the selenic acic to selenous acid again, though, so it has to be taken out.

There are many acids containing chalcogens, including sulfuric acid, sulfurous acid, selenic acid, and telluric acid.

Selenic acid is a stronger oxidiser than sulfuric acid, capable of liberating chlorine from chloride ions, being reduced to selenous acid in the process:
