Today's video is about refining pure silver from 925 silver jewelry. I used nitric acid to dissolve the silver jewelry and then used hydrochloric acid to reduce the silver nitrate to silver chloride. After that, I used sodium hydroxide and sugar to convert the silver chloride into pure silver.
The initial 925 silver jewelry weighed 13 grams, and after refining, I obtained approximately 12 grams of pure silver.
