Germanium sulfide is white orthorhombic crystal, which is insoluble in strong acid. When put it in aqua regia, it would resolve and dissolve in hot solution of alkali metal hydroxide and ammonium hydroxide. When heating to 260~280℃, germanium sulfide would be oxidized. When it reacted with hydrogen peroxide, germanium dioxide is got. Germanium(II) sulfide is customizable.
