[6] [7] At least two modern reproductions of Scheele's green hue with modern non-toxic pigments have been made, with similar but non-identical color coordinates: one with hex#3c7a18 (RGB 60, 122, 24) and another with hex#478800 (RGB 71, 136, 0). [8] [9] The latter is the more typically reported color coordinate for Scheele's green. [10]
Sodium arsenite can be inhaled or absorbed through the skin. Along with its known carcinogenic and teratogenic effects, contact with the substance can yield symptoms such as skin irritation, burns, itching, thickened skin, rash, loss of pigment, poor appetite, a metallic or garlic taste, stomach pain, nausea, vomiting, diarrhea, convulsions, decreased blood pressure, and headache.
Sodium dihydrogen arsenate is the inorganic compound with the formula NaH 2 AsO 4. Related salts are also called sodium arsenate, including Na 2 HAsO 4 (disodium hydrogen arsenate) and NaH 2 AsO 4 (sodium dihydrogen arsenate). Sodium dihydrogen arsenate is a colorless solid that is highly toxic. The salt is the conjugate base of arsenic acid: H ...
Arsenic poisoning is a global problem arising from naturally occurring arsenic in ground water. The evidence that arsenic may be a beneficial nutrient at trace levels below the background to which living organisms are normally exposed has been reviewed. [3]
Arsenic pigments. Realgar: As 4 S 4 - a highly toxic natural pigment. Cadmium pigments. Cadmium red (PR108): cadmium sulfo-selenide (Cd2SSe). Cerium pigments. Cerium sulfide red (PR265). Iron oxide pigments. Sanguine, Caput mortuum, Indian red, Venetian red, oxide red (PR102). Red ochre (PR102): anhydrous Fe 2 O 3.
Sodium arsenate is the inorganic compound with the formula Na 3 AsO 4. Related salts are also called sodium arsenate, including Na 2 HAsO 4 (disodium hydrogen arsenate) and NaH 2 AsO 4 (sodium dihydrogen arsenate). The trisodium salt is a white or colourless solid that is highly toxic. It is usually handled as the dodecahydrate Na 3 AsO 4. 12H ...
Ortho-arsenite contrasts to the corresponding anions of the lighter members of group 15, phosphite which has the structure HPO 2− 3 and nitrite, NO − 2 which is bent. [1] A number of different arsenite anions are known: AsO 3− 3 ortho-arsenite, an ion of arsenous acid, with a pyramidal shape [1] (AsO − 2) n meta-arsenite, a polymeric ...
An arsenate arsenite is a chemical compound or salt that contains arsenate and arsenite anions (AsO 3 3-and AsO 4 3-). These are mixed anion compounds or mixed valence compounds. Some have third anions. Most known substances are minerals, but a few artificial arsenate arsenite compounds have been made. Many of the minerals are in the Hematolite ...
