Why are silver alloys used in jewelry making instead of pure silver?
Silver is a soft metal, so it is often combined with supplementary metals such as copper, nickel, cadmium, palladium, and zinc in jewelry making to make the jewelry tough. Sterling silver, which is durable and used in jewelry making, is an alloy consisting of 92.5% pure silver and 7.5% other metals.
Why is it necessary to determine the silver content in silver jewelry?
Any silver ornament which is less than 90% purity of fine silver is considered low standard. Thus, to ensure the quality of silver ornaments, determining silver content in silver jewelry is crucial. Ensuring the purity of silver ornaments is thus important for an efficient hallmarking procedure.
How do you determine silver content using titration?
Silver content can be determined by argentometric titration using potassium bromide as a titrant with a DMi141-SC electrode and EasyPlus titrator.
