Uses. The major use is in protecting and changing the color of steel, especially steel parts on firearms. The so-called cold-bluing process uses selenous acid, copper(II) nitrate, and nitric acid to change the color of the steel from silver-grey to blue-grey or black.

Is sodium selenate good for you?
Chronic exposure to sodium selenate can cause severe lung, kidney, and liver damage. Overexposure to selenium in the diet leads to a condition known as selenosis. Selenosis occurs at blood levels greater than 100 µg/dL.
What is sodium selenate used for?
Use. Sodium selenate is an insecticide used in horticulture for the control of mites, aphids, and mealybugs. It is also used as a fungicide (ATSDR, 1996).
Does selenic acid dissolve gold?
It is a very strong acid. It reacts with hydrochloric acid to make chlorine and selenous acid. It can dissolve gold to make gold selenate.
What is the PH of selenic acid?

What is the charge for Selenate?
+6
Selenate. Selenate is a polyanion made up of Se and oxygen. The Se ion has a charge of +6 and is bound to four oxygen ions, forming a polyanion with a net charge of (-2).
Is sodium selenate an ionic compound?
Sodium selenite is a chemical compound. Its chemical formula is Na2SeO3. It contains sodium and selenite ions.
What is the difference between sodium selenite and selenium?
One study found that sodium selenite causes oxidative stress, but selenomethionine doesn’t. This study also found that tissue levels of selenium were higher in subjects who had ingested selenomethionine, which suggests that this substance has higher bioavailability than sodium selenite.
Why is sodium selenite bad for you?
* Sodium Selenite may damage the testes (male reproductive glands). * High exposure can cause headache, nausea, vomiting, coated tongue, metallic taste, and a garlic odor of the breath. * Repeated exposures can cause pallor, dizziness, nervousness, and mood changes. * Sodium Selenite may damage the liver and kidneys.
Is it safe to take selenium everyday?
When taken by mouth: Selenium is likely safe when taken in doses less than 400 mcg daily, short-term. But selenium is possibly unsafe when taken in high doses or for a long time. Taking doses above 400 mcg daily can increase the risk of developing selenium toxicity.
What is selenium yeast good for?
European Food Safety Authority (EFSA) approval for human health claims linking dietary intake of selenium yeast to “protection of DNA, proteins and lipids from oxidative damage, normal function of the immune system, normal thyroid function and normal spermatogenesis.”
Is selenate an acid or base?
Selenate. Unlike sulfate, selenate is a somewhat good oxidizer; it can be reduced to selenite or selenium . In strongly acidic conditions, the hydrogen selenate ion, HSeO− 4, is formed. It corresponds to the selenic acid, H 2 SeO 4, which is a strong acid and can in its concentrated form dissolve gold .
What is selenic acid?
Selenic acid is an organic compound with the chemical formula H2SeO4. It may be found in over-the-counter daily dietary supplements as a source of [DB11135], an essential trace mineral for human health. Conformer generation is disallowed since MMFF94s unsupported element Computed by Lexichem TK 2.7.0 (PubChem release 2021.05.07)
What is the difference between La(hseo4)3 and H selenate-selenate?
It is worthwhile to mention, that in contrast to La (HSeO 4) 3, the OH group of the hydrogen selenate ion is coordinated to a metal ion in the structure of the hydrogen selenate-selenates. A unique acidic selenate is the mixed hydrogen selenate-diselenate Nd (HSeO 4 ) (Se 2 O 7) (Wickleder, 2001).
What is the name of the ionic compound with the formula selenate?
The selenate ion is SeO 2− 4. Selenates are analogous to sulfates and have similar chemistry. They are highly soluble in aqueous solutions at ambient temperatures. Unlike sulfate, selenate is a somewhat good oxidizer; it can be reduced to selenite or selenium. In strongly acidic conditions, the hydrogen selenate ion, HSeO − 4, is formed.
