Magnesium pyroarsenate

As Magnesium Pyroarsenate. The arsenic must be present as arsenate, so that any arsenite must first be oxidised, for example by... [Pg.313]

Estimation Gravimetrically as Sulphide as Magnesium Pyroarsenate—Volu-metrically by Iodometric Methods with Potassium Bromate, etc.—The Marsh Test—The Gutzeit Test—Fleitmann s Test—Colorimetric Methods— Microohemioal Methods—Determination of Arsenic in Gases. [Pg.366]

If the test is made with the sulphide precipitated in acid solution, only mercury will interfere by converting the arsenic into magnesium ammonium arsenate and heating to redness, the pyroarsenate Mg2As207 remains and any mercury salts present are volatilized. This forms the basis of a delicate test for arsenic. [Pg.225]
