Electrical magnesium compounds

Preparation. Boron carbide is most commonly produced by the reduction of boric oxide with carbon in an electric furnace between 1400 and 2300°C. In the presence of carbon, magnesium reduces boric oxide to boron carbide at 1400—1800°C. The reaction is best carried out in a hydrogen atmosphere in a carbon tube furnace. By-product magnesium compounds are removed by acid treatment. [Pg.220]

Analyzing and Concluding Did the magnesium compounds and water conduct an electric current Do the results indicate whether or not the compounds are ionic ... [Pg.32]

Design an Experiment If the magnesium compounds conduct a current in solution, can you affect how well they conduct electricity If they did not conduct a current, could they Design an experiment to find out. [Pg.230]

The electrical conductivities of soln. of a great many compounds in liquid hydrogen halides have been measured by E. H. Archibald and D. McIntosh. The conductivity is raised considerably by phosphoryl chloride. Sodium sodium sulphide, borate, phosphate, nitrate, thiosulphate, and arsenate chromic anhydride potassium nitrate, hydroxide, chromate, sulphide, bisulphate, and ferro- and ferri- cyanide ammonium fluoride and carbonate j rubidium and caesium chloride magnesium sulphate calcium fluoride ... [Pg.179]
