I just disolved 500g of fine silver crystal from a previous cell refining batch, solution was colorless and free of any nitric. I've added the 600ml of solution to 3l of what I beleved to be distiled water, which I found was reversed osmosis treaded water and the solution turned brown and cloudy. Does anyone know what could have happened here? I had in mind this could have something to do with sulfur but that's just a guess.
