I wanted to dissolve some iron and try the coloidal experiment on it.
I didnt have any clean Iron to work with so I just messed around with what I had.
one piece may have had some chrome on it so who knows what is coming out?
Anyhow below is a video of what was done. I refer to the precipitate at the botton as sediment,
and the precipitate on top as the floaty stuff .
Just to make it clear the liquid in the jar is from the measured first experiment the liquid in the
flask is the result of using all the sediment material that was left.
If anyone knows what the milky substance was I would love to know.
It has a consistency of thin yogurt and when I added some sodium hydroxide to nutralise the
acid it set, but returned to a liquid overnight.
