The video presents a simple and affordable method for cleaning silver from unnecessary metals and impurities. And since the method of etching silver from unnecessary metals is already widely used with the help of Aqua regia, that is, with the addition of hydrochloric acid. Silver in Aqua regia does not dissolve, and other metals pass into the solution. Hydrochloric acid is only needed to prevent silver from dissolving, and the working acid for dissolving nitric acid. I believe that in this case, the use of hydrochloric acid is an unnecessary waste, especially hydrochloric acid is a precursor. Ordinary kitchen table salt perfectly copes with this task, passivates the surface of silver with a thin layer of silver chloride, thereby preventing its dissolution. In the process, there were nuances and corrections, in particular, the silver was covered with a dirty coating. All the details are in the video. Enjoy your viewing!
