Arsenic forms colorless, odorless, crystalline oxides As 2 O 3 ("white arsenic") and As 2 O 5 which are hygroscopic and readily soluble in water to form acidic solutions. Arsenic(V) acid is a weak acid and the salts are called arsenates , [ 5 ] the most common arsenic contamination of groundwater , and a problem that affects many people.
Other reactions of main group compounds with yellow arsenic have been shown to involve units of arsenic with more than four atoms. In reaction with the silylene compound [PhC(NtBu) 2 SiN(SiMe 3) 2], an aggregation of As 4 was observed to form a cage compound of ten arsenic atoms, including a seven-membered arsenic ring at its center.

The recommendations describe a number of different ways in which compounds can be named. These are: compositional naming (e.g. sodium chloride) substitutive naming based on parent hydrides (GeCl 2 Me 2 dichlorodimethylgermane) additive naming ([MnFO 3] fluoridotrioxidomanganese) Additionally there are recommendations for the following:
It is also present in the form of refined sugars including granulated sugars (white crystalline table sugar, brown sugar, confectioner's sugar, and turbinado sugar), refined crystalline fructose, as high fructose corn syrups as well as in honey. About 10% of the calories contained in the Western diet are supplied by fructose (approximately 55 g ...
Structural formulae (Fischer projections) of fructose (left) and glucose (right) High-fructose corn syrup (HFCS), also known as glucose–fructose, isoglucose and glucose–fructose syrup, [1] [2] is a sweetener made from corn starch. As in the production of conventional corn syrup, the starch is broken down into glucose by enzymes.
These compounds have structures similar to the phosphorus sulfides. Arsenic-arsenic bonds are very weak, and oligomeric arsenic compounds are even more liable to oxidize than their hydrogenated precursors. [6]: 318–320 The following reaction can, however, be prepared through electrochemical reduction in a zinc-sulfate cell.
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.
Dense inverted sugar syrup (Trimoline) Inverted sugar syrup, also called invert syrup, invert sugar, [1] simple syrup, sugar syrup, sugar water, bar syrup, syrup USP, or sucrose inversion, is a syrup mixture of the monosaccharides glucose and fructose, that is made by hydrolytic saccharification of the disaccharide sucrose.
