Question

can somebody please tell me what is arsenic and for what purpose is it used.where can one get that

Answer 1

Arsenic is a metal. Its salts are deadly poisonous.
But homoeopaths use Arsenicum ie a 100000th part of aresical salt as medicine. They claim it cures some diseases.

Answer 2

Arsenic is very similar chemically to its predecessor, phosphorus. Similar to phosphorus, it forms colorless crystalline oxides As2O3 and As2O5 which are hygroscopic and readily soluble in water to form acidic solutions. Arsenic (V) acid, like phosphoric acid, is a strong acid. Like phosphorus, arsenic forms an unstable, gaseous hydride: arsine (AsH3). The similarity is so great that arsenic will partly substitute for phosphorus in biochemical reactions and is thus poisonous. However, in subtoxic doses, soluble arsenic compounds act as stimulants, and were once popular in small doses as medicinals by people in the mid 18th century.

When heated in air it oxidizes to arsenic trioxide; the fumes from this reaction have an odor resembling garlic. This odor can be detected on striking arsenide minerals such as arsenopyrite with a hammer. Arsenic and some arsenic compounds can also sublime upon heating, converting directly to a gaseous form without an intervening liquid state. Elemental arsenic is found in many solid forms: the yellow form is soft, waxy and unstable, and is made of tetrahedral As4 molecules similar to the molecules of white phosphorus. The gray, black or 'metallic' forms have somewhat layered crystal structures with bonds extending throughout the crystal. They are brittle semiconductors with a metallic luster. The density of the yellow form is 1.97 g/cm³; rhombohedral 'gray arsenic' is much denser with a density of 5.73 g/cm³; the other metalloidal forms are similarly dense.

Answer 3

Arsenic is a poisonous metal. It is often used as a slow poison. It can be detected several years after death, especially in the hair and nails. It was previously used as an aphrodisiac, in very small amounts.

Answer 4

arsenic is a metal. its large amount of consumption causes acute toxication & death. long term consumption in very small amount may cause slow poisining.
it also use in some ayurvedic prepetations for treatment purposes.
