Ferrous chloride crystals left in open air
SORRY, BUT THIS IS THE FIFTH TIME this year that I have tried to upload images: My images are trimmed to 400kb and max 400px on longest side and this
forum server will not accept them. So the explanation below is pointless without the image.
Hi, I know not spectacular, but thought it interesting. At least I had not expected this. Ferrous chloride with no apparent oxidation taking place
to ferric chloride - at least no observable change yet.
I filtered the ferrous chloride solution having heated it down to a bare minimum of solution, but with just a few iron filing scrap left over. The
wet sodden green mash that I collected in the filter was full of ferrous chloride and iron particles mixed together. The solution itself remained an
olive green.
I left the solids outside for two days in 3 - 8 c temperatures uncovered and the solids have evaporated quite some water to be left with a reasonably
dry mass of ferrous chloride. Though I know it is by no means pure. You can see the Elemental Iron particles trapped within the crystals though not
so clear on the image attached.
What I did not expect was first that any evaporation would take place, also I expected a little hydrolysis due to the wet atmosphere in the weather,
and lastly I expected this to turn brown and at least show signs of it oxidizing. The presence of elemental iron explains why it is not oxidising?
Not that I mind, this was all just a side show to something else I am busy with.
