• Resumen

  • The use of ascorbic acid (vitamin C) to reduce aqueous diamminesilver(I) chloride is suggested as a means of reducing the hazardousness of reagents and waste in the confirmatory test for silver ion in the group I qualitative analysis scheme. This eliminates the use of nitric acid in the most widely used qualitative analysis scheme and is less problematic than other alternatives previously suggested.
