Linear Formula: Na2SeO3
Sodium selenite is the inorganic compound with the formula Na2SeO3.
Sodium selenit is a colourless solid.
Sodium Selenite are selenious acid, disodium salt.
Sodium selenit is used therapeutically to supply the trace element selenium.
The pentahydrate Na2SeO3(H2O)5 is the most common water-soluble selenium compound.
Synthesis and fundamental reactions of Sodium selenit:
Sodium selenite usually is prepared by the reaction of selenium dioxide with sodium hydroxide:
SeO2 + 2 NaOH → Na2SeO3 + H2O
The hydrate converts to the anhydrous salt upon heating to 40 °C.
According to X-ray crystallography, both anhydrous Na2SeO3 and its pentahydrate feature pyramidal SeO32−.
The Se-O distances range from 1.67 to 1.72 Å.
Oxidation of this anion gives sodium selenate, Na2SeO4.
Applications of Sodium selenit:
Together with the related barium and zinc selenites, sodium selenite is mainly used in the manufacture of colorless glass.
The pink color imparted by these selenites cancels out the green color imparted by iron impurities.
Because selenium is an essential element, sodium selenite is an ingredient in dietary supplements such as multi-vitamin/mineral products, but supplements that provide only selenium use L-selenomethionine or a selenium-enriched yeast.
The US Food and Drug Administration approved a selenium supplement to animal diets; the most common form is sodium selenite for pet foods.
According to one article, "not much was known about which selenium compounds to approve for use in animal feeds when the decisions were made back in the 1970s .
At the time the regulatory action was taken, only the inorganic selenium salts (sodium selenite and sodium selenate) were available at a cost permitting their use in animal feed.”
Sodium selenite has been proposed as an effective suicide agent.

Safety of Sodium selenit:
Selenium is toxic in high concentrations.
As sodium selenite, the chronic toxic dose for human beings was described as about 2.4 to 3 milligrams of selenium per day.
In 2000, the U.S. Institute of Medicine set the adult Tolerable upper intake levels (UL) for selenium from all sources - food, drinking water and dietary supplements - at 400 μg/day.
The European Food Safety Authority reviewed the same safety question and set its UL at 300 μg/day.
Sodium selenite (Na2SeO3) is a toxic inorganic salt that is highly soluble in water and insoluble in organic solvents.
The crystal structure of the anhydrous salt has been variously reported as tetragonal or monoclinic.
In 1889, Irish chemists Sir Charles A. Cameron* and John Macallan produced Na2SeO3 and the previously unknown selenium oxychloride (SeOCl2) by heating selenium oxide (SeO2) with sodium chloride.
This finding was reported in a pioneering series of articles on selenium chemistry.
In an improved 1929 synthesis, J. B. Krak at the Roessler and Hasslacher Chemical Co. (Perth Amboy, NJ) prepared Na2SeO3 by evaporating a solution of sodium hydroxide and selenious acid (H2SeO3) at 60–100 °C.
Commercial Na2SeO3 is now made by heating an aqueous solution of SeO2 and NaOH to form its pentahydrate, which is crystallized and then warmed to 40 °C to liberate the anhydrous salt.
Na2SeO3 and other selenite salts are used to “neutralize” green impurities during the manufacture of colorless glass.
Iron-containing impurities in the natural silicas (e.g., sand) used to make glass absorb red and blue wavelengths of light, giving it a green appearance.
Selenites have no color; but when they are dissolved in the glass mixture, they appear pinkish, counteracting the green hue and making the glass colorless.

HEALTH HAZARD INFORMATION of Sodium selenit:
Acute Health Effects:
The following acute (short-term) health effects may occur immediately or shortly after exposure to Sodium Selenite:
* Contact can severely irritate and burn the skin and eyes with possible eye damage.
* Breathing Sodium Selenite can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath.
Chronic Health Effects:
The following chronic (long-term) health effects can occur at some time after exposure to Sodium Selenite and can last for months or years:
Cancer Hazard:
* Sodium Selenite may cause mutations (genetic changes).
* There is no evidence that Sodium Selenite causes cancer in animals. This is based on test results presently available to the New Jersey Department of Health and Senior Services from published studies.
Reproductive Hazard:
* Sodium Selenite may damage the developing fetus.
* Sodium Selenite may damage the testes (male reproductive glands).
Other Long-Term Effects:
* 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.
* Long-term exposure can damage the red blood cells causing anemia (low blood count).
MEDICAL:
Medical Testing:
Before beginning employment and at regular times after that, the following is recommended:
* Urine test for Selenium (should be less than 100 micrograms per liter of urine).
If symptoms develop or overexposure is suspected, the following are recommended:
* Complete blood count.
* Liver and kidney function tests.
Any evaluation should include a careful history of past and present symptoms with an exam.
Medical tests that look for damage already done are not a substitute for controlling exposure.
Request copies of your medical testing.
You have a legal right to this information under OSHA 1910.1020.
Mixed Exposures:
* Because smoking can cause heart disease, as well as lung cancer, emphysema, and other respiratory problems, it may worsen respiratory conditions caused by chemical exposure.
Even if you have smoked for a long time, stopping now will reduce your risk of developing health problems.
* Because more than light alcohol consumption can cause liver damage, drinking alcohol can increase the liver damage caused by Sodium Selenite.

Selenium is a component of glutathione peroxidase enzyme, which protects cell components from oxidative damage due to peroxides produced during cellular metabolism.
Selenium (Se) has been demonstrated to prevent cancer in numerous animal models when administered selenium at levels exceeding the nutritional requirements.
One study showed efficacy in the prevention of malignancy while utilizing a selenium supplement in humans.
The reports from such studies have heightened the interest in additional human selenium supplementation studies to validate the results in larger populations.
