Precipitated Silver: Silver Chloride Reduced by Zinc in Acidulated Water (Thorpe 1913)

Fine silver powder without melting anything. Hydrochloric acid throws silver out of solution as white silver chloride. Zinc in slightly acid water then takes the chlorine away and leaves the silver as a grey powder. Source: Thorpe, Dictionary of Applied Chemistry, vol. 4 (1913), Silver. Thorpe gives no amounts, times or end-point. Ours: a silver nitrate solution, zinc sheet strips, hydrochloric acid of the two acids he names, and the washing and drying. Picture drawn by Youblob.

Throw down silver chloride with hydrochloric acid

Add hydrochloric acid to the solution. White silver chloride falls. Ours: add it while it still makes a precipitate, let it settle and pour off the liquid.

Reduce the chloride with zinc in acid water

Cover the chloride with water made slightly acid with hydrochloric acid (Thorpe: hydrochloric or sulphuric) and put zinc in it. The zinc reduces the chloride to silver. Ours: strips of zinc sheet, left in until no white chloride is left. Time not given.

Take out the zinc, wash and dry the silver

Ours: lift out what is left of the zinc, wash the grey silver powder with water until the washings are no longer acid, filter, and dry it. Keep it in a closed jar.
