B&S used to ship silver nitrate in small brown bottles. Then at some point they switched to big (for 30 grams) white plastic bottles. One of those plastic bottles got pushed behind the other chemistry in my covert and I lost track of it and I re-ordered without knowing that I had it. When I rediscovered it the crystals had turned a grey color. I don't know how long ago that I had ordered it but it can't be too long. It was kept with the cap tightly closed in a dark place and never openly exposed to the environment. Could the white plastic container be the cause of the color change? Having used the last of working solution this morning, I mixed up another 100mL of working solution. I found a small brown bottle with ~3.5 gms in it and used it along with SN in another white brown bottle plastic bottle. Both had good color but I can't remember if the brown bottle was from last order or not.
