Two important uses of precipitation reactions are to isolate metals that have been extracted from their ores and to recover precious metals for recycling. However, ammonium sulfide is unstable and will rapidly decompose into hydrogen sulfide and ammonia. Toxicity is represented by the complete cessation of methanogenic activity, and inhibition occurs as a result of reducing the rate and extent of methanogenesis. Thus washing the film with thiosulfate solution dissolves unexposed silver bromide and leaves a pattern of metallic silver granules that constitutes the negative. So when I look at my options of copper carbonate or a potassium nitrate, what I see is that potassium nitrate is soluble, it would not be solid, it would be aqueous. * There are 9 crystalline forms of zinc chloride.
