I tried to convert my silver chloride with lye and sugar. The moment the AgCl turned black, I let it rest for a couple of minutes, then added granulated cane sugar, and a little syrup made from glucose and sugar.
The result was a pitch black liquid with lots of small flakes. After adding hot water, I let it rest, decanted the water and added new water, but the liquid stays black and now I have this 3 cm layer of black precipitant.
I am doing something wrong, that's obvious. Did I add too much lye, or did I use the wrong and or too much sugar ?
I now understand normal granulated sugar, even in a watery solution will do the trick, and have to add it slowly, things I will do from now on. But what is this black fluffy precipitant, and how is it created ?
