Magnesium arsenate has lost its industrial importance because of the toxicity of arsenic. [Pg.248]

Cadmium, zinc, magnesium, arsenic, and phosphorus have also an inducing effect similar to that of the alkali metals. With the divalent metals the mechanism whereby the chain is initiated is... [Pg.168]

A light form of magnesium arsenate may be obtained by heating a slurry of magnesium hydroxide with the theoretical quantity of arsenic acid and 15 per cent, of the equivalent amount of sodium hydroxide in an autoclave at 180° C. until the filtrate contains less than 0-2 per cent, of arsenic pentoxide.3... [Pg.209]

The property of adherence of dusts to the plants determines their effectiveness. It varies considerably with composition, lead hydrogen arsenate adhering to a greater extent than magnesium arsenate and this more than calcium arsenate. The presence of slaked lime reduces the adherence.2 The air condition at the time of dusting also has an effect, the adhesion decreasing with increased wind velocity.3... [Pg.302]

The carbonates, sulphates, and borates are decomposed. The sulphides of the alkalies and alkaline earths are decomposed while the sulphides of arsenic, antimony, molybdenum, zinc, cadmium, tin, iron, lead, copper, mercury, and palladium are not attacked. Cobalt sulphate is not attacked, while the sulphates of the alkalies and alkaline earths are attacked and dissolved. Alkali tungstates, ammonium arsenite and arsenate, copper arsenite, ammonium magnesium arsenate, ammonium molybdate and vanadate, potassium cyanide and ferrocyanide are decomposed. Paraffin is not attacked shellac, gum arabic, gum tragacanth, copal, etc., are decomposed. Celluloid is slowly attacked. Silk paper, gun cotton, gelatin, parchment are dissolved. M. Meslans 22 has studied the esterification of alcohol by hydrofluoric acid. [Pg.134]

Solubility of Ammonium Calcium Arsenate and Ammonium Magnesium Arsenate in Water, etc. [Pg.20]

A reaction mixture in this equilibrium was prepared, in which H3ASO3 was labeled with As. The exchange was quenched by dilution with water and addition of an excess of ammonium hydroxide. The As04 ions were precipitated as ammonium magnesium arsenate and subjected to activity measurement. The rates of oxidation and reduction measured in this way were in agreement with the kinetic expressions and rate constants, which hold for the same reaction remote from equilibrium. [Pg.1783]

Cohalt arsenates are generally reported to he the components of some pigments referred to as cobalt violet (q.v.) however, recent work on these pigments has identified magnesium cobalt arsenate as the more hkely constituent (Corbeil et al., 2002). Magnesium arsenate is isostructural with cobalt arsenate, and substitution between the two compounds is likely. [Pg.112]
