Gold selenates

No thermodynamic data have been found for gold selenates. [Pg.310]

More recently, the direct synthesis of methanol from methane, using metallic gold as catalyst, was reported, involving a purported CH3-Au intermediate. Selenic acid was used as a stoichiometric oxidant as it is known to oxidize gold metal. Moderate turnovers (30) were achieved (Equation (6)).14... [Pg.104]

The above proportions of palladium and gold correspond to the formula PdAus. A natural selenide of palladium, Eugenesite or selen-palladium, has been described 3 as a silver-white, hard, crystalline alloy, which can be readily melted. [Pg.174]

Auric selenate, Au2(Se04)3.—At 230° to 300° C. gold dissolves in concentrated selenic acid, with formation of auric selenate and selenious acid. The salt forms yellow crystals, insoluble in water, but soluble in concentrated acids.3... [Pg.348]

Oxoacid salts of gold are uncommon one of the more stable, yellow Au2(Se04)g, crystallises from a solution of gold in hot selenic acid. [Pg.521]

Selenic acid (H2Se04) is a powerful oxidizing acid that dissolves not only silver (as does the related acid H2SO4) but gold, through the following reaction ... [Pg.478]

Selenic acid is said to be the only acid which in pure aqueous solution will attack gold. Perform experiments to see if it will attack, gold leaf. [Pg.149]

Just as SO2 can be a noxious component of polluted air, SeO also is a very disagreeable gas its odor has been described as that of rotten horseradish. Selenic acid (H SeO ) is very reactive it is such a powerful oxidizing agent that it can even dissolve gold. Solid selenium is soluble in concentrated H SO. The result is a green solution of SeSO,. [Pg.160]
