Head to https://squarespace.com/amateurchemistry to save 10% off your first purchase of a website or domain using code AMATEURCHEMISTRY In this video I refine old silver jewelry using homemade nitric acid to obtain some silver metal which I then magically transform into a high quality mirror while trying hard not to contaminate everything with copper. If you enjoyed the video consider liking it, sharing it with a friend, and subscribing to my channel - I would really appreciate that :) If you want to further support my work and watch exclusive content here's my Patreon - / amateurchemistry Instagram - / amateurchemistry_ TikTok - / amateur.chemistry Also, excuse me for my poor speaking, English is not my native language so I have some trouble with pronunciation, in case you don't understand something there are always subtitles made by me. Please don't comment about how stupid I am to wear nitrile gloves when handling nitric acid, I am aware of the dangers and don't need hundreds of people trashing the comment section. 0:00 Intro 3:07 Making nitric acid from potassium nitrate 5:00 Dissolving old jewelry in acid 8:40 Melting copper cable 10:12 Separating silver from copper 12:41 Making pure silver nitrate 14:24 Making silver mirrors using Tollen's Reagent 18:38 Outro #chemistry #experiment #beautiful #demonstration #science #interesting #silver #mirror #jewelry #cool #copper #reaction
