Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal.Arsenic is a metalloid.It has various allotropes, but only the gray form, which has a metallic appearance, is important to industry.. The primary use of arsenic is in alloys of lead (for example, in car batteries ...

XPS results have shown that the better mineral separation obtained in this study with H 2 O 2 results from the surface of the arsenic minerals being more oxidised than the non-arsenic minerals. Arsenic oxides are more stable than copper oxides at pH 5.0 but they dissolve less than copper oxide in the presence of EDTA at pH 11.0.

Copper sulfate is a sulfate salt of copper. It is a potent emetic and is used as an antidote for poisoning by phosphorus. It also can be used to prevent the growth of algae.
