If FeCl3 is pure, then the insoluble substance is Fe(OH)3
I agree with what was said above, but I think there’s also iron oxide
The original poster’s description is too vague; details such as the solvent, dissolution conditions, and time are not clear. If it is dissolved in an excess of water, I guess the impurities might be iron hydroxide and iron oxide
Iron hydroxide, iron oxide, unreacted iron shavings; will have them analyzed another day. Last edited by limingshuguang on 2009-4-18 19:12]
Once the chlorine-containing carbon steel pipes are removed, the FeCl3 coating immediately absorbs water; it becomes brown in color, resembles oil, and is acidic – it’s probably iron hydroxide
Any process or reaction takes place under specific conditions; I hope LZ can be more specific~~
:time: Is it possible that the components are SiO2, SiC, etc.?
It should be iron hydroxide or iron oxide.
There is iron hydroxide and iron oxide; if other impurities are present, it is likely that the solution is impure~
Mainly ferrous chloride, as well as water-insoluble substances such as iron hydroxide and iron oxide
