Arsenic trisulfide is the inorganic compound with the formula As 2 S 3. It is a dark yellow solid that is insoluble in water. It is a dark yellow solid that is insoluble in water. It also occurs as the mineral orpiment (Latin: auripigmentum), which has been used as a pigment called King's yellow.
Any arsenic present would appear as arsenic trioxide and then could be subjected to Metzger's test. The most common test (and used even today in water test kits) was discovered by Samuel Hahnemann . It would involve combining a sample fluid with hydrogen sulfide (H 2 S) in the presence of hydrochloric acid (HCl).
Arsenic sulfide may refer to: Arsenic trisulfide , As 2 S 3 , the mineral orpiment Arsenic pentasulfide , As 2 S 5 , similar structure to phosphorus pentasulfide (β-P 2 S 5 )
Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...
A better, alternative method with higher accuracy is available, which involves the addition of excess but known volume of standard sodium arsenite solution to the sample, during which arsenic trisulfide is precipitated: As 2 O 3 + 3 H 2 S → As 2 S 3 + 3 H 2 O
In its standard state arsine is a colorless, denser-than-air gas that is slightly soluble in water (2% at 20 °C) [1] and in many organic solvents as well. [citation needed] Arsine itself is odorless, [5] but it oxidizes in air and this creates a slight garlic or fish-like scent when the compound is present above 0.5 ppm. [6]
Arsenic is also a common n-type dopant in semiconductor electronic devices, and a component of the III–V compound semiconductor gallium arsenide. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining with the ...
In organic and organometallic chemistry, trisulfide is the functional group R-S-S-S-R. Examples include: Diallyl trisulfide; Dimethyl trisulfide; Trisulfane (hydrogen trisulfide) Some inorganic compounds are also named trisulfides to reflect their stoichiometry. Examples include: Antimony trisulfide; Arsenic trisulfide; Bismuth trisulfide ...
