- 中文摘要: Bivalent germanium was polargraphically studied in sodium hydroxide solution at various concentrations. A well-defined reduction wave with half-wave potential varying from -0.90 to -0.98 volt us. S.C.E. was observed for 1×10¯4 M Ge(II) in concentration range of 0.2 to 2.0F with respect to NaOH, and from -0.70 to -0.88 volt us. S.C.E. in the pH range 9.0-12.1 at 25°. The value of id/C is 5.43 μa/mM and that of id/C m2/3 t1/6 is 5.21. Experimental result suggests that the reaction proceeds in two-stepd involving an irreversible two-electron reduction: Ge(OH)2+OH¯→HGeO2¯+H2O and HGeO2¯+H2O+2e→Ge0+3OH¯.
