(1)新撒爾瓦散可以用作銀離子試劑,與銀離子生成棕色絡合物沉澱。I.L.2γC.L.1∶25,000一般陽離子中只Cu~(++)生成橙黃色沉澱,Fe~(+++)生成紫色沉澱,Hg~(++)生成少量棕綠色沉澱,Hg_2~(++)還原成黑色沉澱。 (2)由Job變更濃度法製得光吸收一組成曲線,最高點相當於銀離子與新撒爾瓦散之此為2∶3。 (3)茲建議偶砷基為銀離子的分析功能團。
(1) Neo-Salva powder can be used as a silver ion reagent to generate a brown complex precipitate with silver ions.

(2) The concentration of the law by the Law changes in the concentration of light absorption of a set of curves, the highest point of the equivalent of silver ions and the new Salva scattered this is 2:3. (3) It is suggested that arsenic should be used for the analysis of silver ion functional groups.
