| Abstract: | In the silver electrolysis liquor,free nitric acid is titrated with sodium hydroxide with bromcresol green as indicator; copper is determinde by EDTA compleximetry with acetic acid as buffering agent; and then silver is titrated with sulfocyanate in diluted nitric acid medium. This method is accurate and easy to be operate. |
