About :

In this video you will see one of the easiest ways to get caustic soda that I know. Caustic soda is used in many spheres of human life as a degreaser, to obtain cyanides, to restore gold. Although according to calculations we should have gotten 75 grams of caustic soda, we got only 36 grams, but I think that there were many losses on the filter and during evaporation. At the end of the video you will see a test of the obtained caustic soda for the ability to restore gold from a solution, during the tests it was found that homemade caustic soda works no worse than the factory one. Write to me in the comments what other methods of gold restoration would be interesting for you to see. Thank you. I have always recommended, recommend and will recommend using good laboratory glassware: Distillation apparatus No. 1 http://ali.ski/CINjnm Distillation apparatus No. 2 http://ali.ski/y_j-5 Distillation apparatus No. 3 https://goo.gl/CQD5tZ Super set of glassware No. 1 https://goo.gl/Ht4yoM Super set of glassware No. 2 http://ali.ski/-SOp_ Found not the cheapest Drexel apparatus http://ali.ski/FL5Cnp
