Refining Gold with Sulphuric Acid
The acid was poured off, and distilled water placed on the brown button left. It immediately became white, owing to the precipitation of the silver in solution on the zinc. Ag2 SO4 + Zn = 2Ag + Zn S04. On adding more acid, and boiling, and then washing with water and dilute nitric acid the weight of the bead was 9750. On cupelling it weighed 9658.
