Making Ferrofluid
in Chemistry

hey im new, read your post see, lol, well i have synthesised magnetite nanoparticles, if you add brushed iron wool to fecl3 in boiling water give it 15mins and it turns a clear light green, make sure its not steel, sometimes a chromium ferric complex can form a protective oxidative coating, add this in a fecl3:fecl2 2:1 proportion and a source of OH- ions slowly, fe3o4 is only made in an acidic environment, if too much alkali is added at once a high basic environment will form rust(a good way of making thermite), oleic acid can be separated from olive oil by adding a group 1 hydroxide and then mixing an acid with the filtered resulting solid white mass, glycerine dissolves in water, oil floats, decant free fatty acids and its pretty much 80% oleic acid, i was wanting to use kerosene or mineral oil (due to the less offensive smell), a question i ask, what liquid is not soluble in mineral oil that has a lighter specific gravity, adding a lighter liquid allows spikes to form
