Therefore, the Ba–H bonds in BaH12 have substantial ionic character, whereas the H–H bonds are mainly covalent. The low electronic density of states N(E) in semimetallic Cmc21-BaH12 looks typical for one-dimensional …H–H–H… chains (Fig. 4h, Supplementary Figs. S36 and S38) which...

and is applicable to a wide sulfur concentration range. Although the reaction can be used for the determination of barium ion, its principal application is in sulfur analysis. The experimental procedure for the determination of sulfur is given at the end of this chapter. From the solubility ...
sulfur or carbon and oxygen to form barium compounds. Barium compounds are used by the oil and gas industries to make drilling muds. Barium attacks most metals with the formation of alloys; iron is the most resistant to alloy formation. Barium forms alloys and intermetallic compounds with lead,...
