EXPERIMENT 1
---------------
Arsenate ion and arsenic acid cannot easily be reduced to the element.
Reduction to trivalent arsenic, however, can easily be accomplished with
iodide.
EXPERIMENT 2
---------------
Arsenate does not form thioarsenates when sulfide ion is added. On
acidification, the sulfide is oxidized though by the arsenate.
EXPERIMENT 3
---------------
Arsenic in oxidation state +5 is not easily reduced to elemental arsenic,
except by tin(II) chloride.
EXPERIMENT 4
---------------
Silver(I) ion gives a chocolate brown precipitate with arsenate.
EXPERIMENT 5
---------------
Arsenic in oxidation state +3 is quickly reduced to elemental arsenic by
tin(II) chloride in hydrochloric acid.
