What is the formula for sodium arsenate?
Na3AsO4Sodium arsenate / Formula
Sodium arsenate is the inorganic compound with the formula Na3AsO4. Related salts are also called sodium arsenate, including Na2HAsO4 (disodium hydrogen arsenate) and NaH2AsO4 (sodium dihydrogen arsenate).
What is sodium arsenate used for?
Sodium Arsenate is a clear, colorless crystalline (sugar or sand-like) material. It is used in dyeing and printing, in making other arsenates, and as a germicide. * Sodium Arsenate is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, NTP, DEP, IARC, HHAG and EPA.
What is Na3AsO3?
Sodium arsenite usually refers to the inorganic compound with the formula NaAsO2. Also called sodium meta-arsenite, it is the sodium salt of arsenous acid. Sodium ortho-arsenite is Na3AsO3. The compounds are colourless solids.
What is arsenic salt?
Arsenic(V) acid is a weak acid and the salts are called arsenates, the most common arsenic contamination of groundwater, and a problem that affects many people. Synthetic arsenates include Scheele’s Green (cupric hydrogen arsenate, acidic copper arsenate), calcium arsenate, and lead hydrogen arsenate.
Is sodium arsenite a herbicide?
Sodium arsenite is an inoganic sodium salt with formula with formula NaAsO2. It has a role as an insecticide, an antibacterial agent, a herbicide, a rodenticide, a carcinogenic agent, an antineoplastic agent and an antifungal agent.
What is the formula of arsenic acid?

Is sodium arsenate is poisonous?
* Breathing Sodium Arsenate can irritate the nose and throat. * High exposure can cause poor appetite, nausea, vomiting, stomach cramps, diarrhea and even death. * Sodium Arsenate is a CARCINOGEN in humans. It has been shown to cause lung cancer.
Does na3as2 exist?
No such compound with formula Na3As2 exists because sodium cannot have +2 oxidation state.
Is sodium arsenite poisoning?
Toxicity Sodium and potassium arsenite are highly soluble (trivalent) arsenic salts. Substantial ingestions may be fatal (fatal dose not known). Features Systemic toxicity may follow ingestion, inhalation or topical exposure. Topical – May cause skin irritation and sensitization.
Is arsenic acidic or basic?
Arsenous acid, H3AsO3, which contains trivalent arsenic, is a weak acid with a first dissociation constant of 3.5×10−10 [25].
How much arsenic is in sodium arsenite?
58% arsenic
Sodium arsenite contains 58% arsenic and is very soluble in water and alcohol. The boiling point of sodium arsenite is 100°C, the density is 1.87 and the molecular weight is 129.91. Sodium arsenite is a highly toxic sub- stance with an acute oral LD 50 (mammalian) of 10—50 mg/kg.
How na2so3 is formed?
How do you make sodium sulfite? Sodium sulfite can be prepared by the treatment with sulfur dioxide of a sodium hydroxide solution. The Na2SO3 initially precipitates as a yellow solid when performed in warm water. The solid dissolves with more SO2 to give the disulfite, which crystallizes as it cools down.
Why is sodium Metaarsenite hazardous?
* This chemical is on the Special Health Hazard Substance List because it is a CARCINOGEN, MUTAGEN and TERATOGEN.
What are P block elements?
P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
