What is the approximate ratio of the solubility of CaSO4 (Ksp = 2.4 x 105) in pure water to the solubility of CaSO4 in 0.10 M Na2SO4 at the same temperature? Arsenic trioxide, As 2 O 3, is an odorless white powder that has relatively high solubility in water. https://wwwn.cdc.gov/TSP/MMG/MMGDetails.aspx?mmgid=1424&toxid=3 If the arsenic is not soluble, it will precipitate and remain in the solid phase of the groundwater system as part of the soil. In the 1990s, researchers from China showed complete clinical remissions in two-thirds of patients with acute promyelocytic leukemia (APL) treated with arsenic, and a survival rate of 60% at 7 years. Arsenite and arsenate forms are highly soluble in water.

Sodium Metaarsenite is a highly soluble, orally available trivalent arsenic-containing telomerase inhibitor with potential antitumor activity.Although the exact mechanism through which sodium It plays an essential role in the majority of cellular processes. Very slightly soluble in diethyl ether. Most Arsenic compounds are soluble in water to some extent and thus are easily transported in the blood stream and assimilated by the body. Solubility: p. 4 Partially soluble in cold water, hot water. Arsenic trioxide (As 2 O 3), a by-product of copper refining, Arsenic trioxides are moderately soluble in water and have been used industrially as pigments and pesticides for a long time. Slightly soluble in water, but dissolves very slowly; more soluble in hot water [Merck]. It dissolves in water to make an acidic solution of arsenious acid. Vitamin C (VC) or ascorbic acid is a water-soluble vitamin and antioxidant present in many vegetables and fruits. It decomposes to arsenic trioxide, elemental arsenic and iodine when heated in air at 200 C. Elimination is rapid at first (half-life of 12 days), by methylation to monomethylarsonic acid and dimethylarsinic acid, and excretion in the urine, but a certain amount (3040% in the case of repeated exposure) is incorporated into the bones, the muscles, the skin, the hair and the nails (all tissues rich in keratin) and eliminated over a period ID: A-2054-1L Min.

Arsenic Trioxide, As 2 O 3, is a very good reductometric primary standard but it dissolves slowly in water.When dissolved in an alkali such as Sodium Hydroxide, readily soluble Sodium Arsenite, NaAsO 2, is produced.When this solution is neutralized with an acid, it is then commonly called Arsenious Acid, H 3 AsO 3.. Arsenic Trioxide and its solutions can be used to when you dissolve 0.13203 g of arsenic trioxide in 50 ml of solvent you will get 1000 ug/ml arsenic solution which is 1000 ppm arsenic solution. Arsenic trioxide is not soluble in water or acid but it can be solublezed in form of sodium salt of arsenic trioxide like Na3AsO3. this salt is soluble. If there is a binding site on the soil surface that is available, and the arsenic is in a form that binds strongly, it will also leave the water phase and attach to the soil.
