Contaminants within solution of NH4NO3?
Hello SM!
After months of eyeing it, I finally decided to extract and recrystallize the NH4NO3 from a ~6 year old unused ice pack I had. Yesterday I opened it
up, and I studied the beige pellets of AN within. I dissolved them in around 150mL of tap water, and the solution remain beige/light brown, even after
filtering. I left it on a warm surface to evaporate, and after an hour or two, a white substance could be found on the sides of the beaker, and a
few(3 or 4) small particles, colored not unlike cardboard, were floating around the liquid. Today, some of the particles became larger, and more
appeared, and more of the white substance on the sides of the beaker, were seen, as shown below:
Any idea of what these particles are?
EDIT: I may have posted this in the incorrect forum section, please forgive me.

Most likely, it is iron contamination.

It's usually an anti-caking agent. No idea what compound. Cold packs tend to have them, like the one from NurdRage's potassium nitrate video.
Though normally it should've been removed during filtration. Could be iron or some dye.

Any ideas on removing the impunities? There's quite a lot, and it goes right through the filter paper.
