Arsenic acid, H3AsO4, is the acid form of arsenate ion, AsO43-, a trivalent anion. Arsenate salts behave chemically very similarly to the phosphates. An acid (from Arabic Azait meaning oil, often represented by the generic formula AH) is typically a water-soluble, sour-tasting chemical compound. ...
Applications
Arsenic acid is used in wood treatment, finishing agent for glass and metal, in the manufacturing of dyestuffs and organic arsenic compounds and also in soil sterilant. It can moreover be used as a herbicide, insecticide or rodenticide. Image:Http://www. ... An insecticide is a pesticide whose purpose is to kill or to prevent the multiplication of insects. ... Rat poisons are a category of pest control chemicals intended to kill rats. ...
Arsenic and its compounds are used as pesticides, herbicides, insecticides and various alloys.
As the symptoms of arsenic poisoning were somewhat ill-defined, it was frequently used for murder until the advent of the Marsh test, a sensitive chemical test for its presence.
Arsenic and its compound inhibit the enzyme lipothiamide pyrophosphate, which is an important enzyme of metabolism.
Phosphoric acid may be used by direct application to rusted iron or steel tools or surfaces to convert iron(III) oxide (rust) to a watersoluble phosphate compound.
While phosphoric acid has the potential to release three hydrogen ions, in aqueous solution the third requires a high pH because PO is almost as strong a base as hydroxide ion.
The anion associated with phosphoric acid is called the phosphate ion, and is found pervasively in biology, especially in the compounds derived from phosphorylated sugars, such as DNA and RNA and adenosine triphosphate (e.g.
