Note 20 — Chapter XXIV · COPPER, SILVER, AND GOLD
George Kamensky translation
The reaction of Pb(OH)2 upon AgHO in the presence of NaHO leads to the formation of a compound of both oxides, PbOnAg2O, from which the oxide of lead cannot be removed by alkalies (Wöhler, Leton). Wöhler, Welch, and others obtained crystalline double salts, R2AgX3, by the action of strong solutions of RX of the halogen salts of the alkaline metals upon AgX, where R = Cs, Rb, K.
