S has 6 valence electrons and each I atom has 7 valence electrons, for a total of 6 +6 7 = 48 electrons that need to be accounted for. Their structure closely depends upon thermal conditions of synthesis. The ore concentrates are mostly sulfidic; they are converted to the oxides by heating under air in a process known as roasting: Some of the germanium is left in the dust produced, while the rest is converted to germanates, which are then leached (together with zinc) from the cinder by sulfuric acid. [37] The disulfide is appreciably soluble in water and in solutions of caustic alkalis or alkaline sulfides. In the Lewis structure of GeCl4. 1 It can be obtained by the reaction between hydrogen sulfide and germanium tetrachloride in a concentrated hydrochloric acid solution.
