Synthesis of Ferrate and magnetite

[vidbid1]

Could I use the rust from some steel nails to make magnetite?

[LackOfFuel]

I assume one can use sodium hydroxide instead of ammonia?

Tesco supermarket is a world wide market?

How do you make ferric chloride? I have hydrochloric acid is that all i need?

You made a very interesting video, i like it!

I also made K2FeO4 in my own lab: I have mixed FeCl3, KOH, K2S2O8 - solution and it works much better than with bleach. I got a real beautiful, intensive violet solution, it looks like KMnO4. When i add solid sodium-disulfite to the solution, the solution turns from violet to green. when i shake it, it turns yellow!

@32SanX cool, yeah i tryed to reducse it with sugar and it did not work, might try what you did sounds interesting

[GingyPno123]

@32SanX You can also heat iron powder with potassium nitrate. 2KNO3 + Fe ------> K2FeO4 + N2 + O2.

[32SanX]

@GingyPno123 Yes, I know a lot of methods how to make ferrates, because i quite like iron compounds. I don't like this method, because it is too dangerous for me. (I hate flash-powder-reactions) I also read about a method which will give a lot of K2FeO4 and a higher purity. A KOH solution is electrosysed with an iron anode, but i haven't tried this yet.

Now drink it! Cheers !!! lol

I have found when preparing magnetite, if you make up your FeCl2 in 1-2M HCl, it helps to keep it from being oxidized to Fe(III)

[mewrox99]

You love woelen's site lol

[AlchemicalGarden]

@mewrox99 tis the shit

[hkparker]

Your explanations of the reactions are great. My high school chem teacher told me the iron (IV) ion isnt very understood and that the iron atoms have really interesting charges. Anyway, ive made a thermite out of Iron (IV) oxide before, cool stuff.

[AlchemicalGarden]

@hkparker yeah its super stuff, when i had got the pink soultion i tryed to reduce it with sugar (as in the permange and sugar, were you get the colours) but nothing happened, i probebly should have tryed a diffferernt reducing agent, maybe thiosulphate.

[hkparker]

@AlchemicalGarden Ive always used a solution of sugar and lye to reduce the permanganate ion, but my sugar is not a reducing sugar. Thiosulfate seems like it would've worked, I dont know, maybe youl have to try it again?

[AlchemicalGarden]

@hkparker would seem like the thing to do. look at me still talking when there science to do....

[Zink575]

@hkparker Iron (IV) Oxide hasnt even been isolated yet. Was that Roman Numeral confusion or an equation confusion? Iron comes in 3 oxides. Iron(II) oxide, Iron(III) Oxide, and Iron(II),(III) Oixide

[hkparker]

@Zink575 By Iron (IV) I mean, Iron (II),(III) oxide, its another way to write it.

[Zink575]

@hkparker No, that is not another way to write it. At least, not a correct way. Iron(IV) Oxide would be FeO2.

[hkparker]

@Zink575  I was taught wrong, thank you for th correction.

Epic video

[RoelMansje]

Nice vid, as usual ;)

[ignilc]

damn, you know the work!

[reubenthorpe1992]

i love look around you

[BarrioX5]

man I love your stuff:) keep it up brother:)

[sciencoking]

Are there also elements which are only magnetic if ionized?

[AlchemicalGarden]

@sciencoking Well yeah sort of, iron is a Ferro magnet, that is the magnesium come from the nucleus. These are the strongest magnets. There’s also paramagnetism and diamagnetism and these are to do with paired or unpaired electrons giving rise to magnetic properties. But as I said Im not to hot on this subject.
