Neosalvarsan is proposed as a reagent for silver ions.It forms a brown insoluble complex.I.L.2γ; C.L.25,000.By Jab's continuous variation method,light absorption-composition curves were obtained.The maximum corresponds to silver:neosalvarsan=2:3.It is proposed that the-As=As-group may be considered as an analytical functional group for silver ions.
