Binary acids are often contrasted with oxyacids, which are acids that contain oxygen and other compounds. However, other categories of acids remain in widespread use, including carboxylic acids. In addition, there are subcategories of binary acids, such as hydrohalic acids, which are binary acids where X is one of the halogens.
Most of the commonly encountered acids are oxyacids. [3] Indeed, in the 18th century, Lavoisier assumed that all acids contain oxygen and that oxygen causes their acidity. Because of this, he gave to this element its name, oxygenium, derived from Greek and meaning acid-maker, which is still, in a more or less modified form, used in most ...
Binary compounds of the group can be referred to collectively as pnictides. Magnetic properties of pnictide compounds span the cases of diamagnetic systems (such as BN or GaN) and magnetically ordered systems (MnSb is paramagnetic at elevated temperatures and ferromagnetic at room temperature); the former compounds are usually transparent and ...
Polysulfuric acids including disulfuric acid (pyrosulfuric acid) H 2 SO 4 ·nSO 3 +6 Disulfate (commonly known as pyrosulfate), S 2 O 2− 7 and trisulfate, S 3 O 2− 10: Pure disulfuric acid melts at 36 °C. Present in fuming sulfuric acid, oleum. Examples known for n = 1 and n = 2. Peroxymonosulfuric acid: H 2 SO 5 +6 Peroxomonosulfate, OOSO ...
These acids, and their esters and salts ("phosphates") include some of the best-known and most important compounds of phosphorus. Orthophosphoric acid, H 3 PO 4. The simplest member of this class is: Phosphoric acid proper (also called orthophosphoric acid or monophosphoric acid), H 3 PO 4 (or OP(OH) 3), a triprotic acid.
By contrast, the univalent anions perchlorate and permanganate ions are very difficult to protonate and so the corresponding acids are strong acids. Although acids such as phosphoric acid are written as H 3 PO 4, the protons are attached to oxygen atoms forming hydroxyl groups, so the formula can also be written as OP(OH) 3 to better reflect ...
Sulfonic acids, such as p-toluenesulfonic acid (tosylic acid) are a class of strong organic oxyacids. [7] Some sulfonic acids can be isolated as solids. Polystyrene functionalized into polystyrene sulfonate is an example of a substance that is a solid strong acid.
In inorganic chemistry and materials chemistry, a ternary compound or ternary phase is a chemical compound containing three different elements.. While some ternary compounds are molecular, e.g. chloroform (HCCl 3), more typically ternary phases refer to extended solids.
