Why Chemistry Class Is So Fun


#1

Anyone know about ferrofluids? ;D


(Q) #2

What in the world?


(Kei) #3

Whoa… What is it?


#4

A ferrofluid is a polarized fluid that you put a magnet near and it will form crazy shapes and such.


(Q) #5

I was genuinly scared for a moment


(LookAYoYo) #6

it is just liquid magnets. and they are awesome.


(Q) #7

DUH.
I should’ve known that.
FE=Iron
And any substance with iron in it is Ferrous.
Brain fart


#8

iron powder and mineral oil? or something else?


#9

FeO, magnetite precipitated from a complex reaction between NH and a mixture of Ferric Chloride and Ferrous Chloride. The carrier fluid is kerosene and the surfactant is oleic acid.

Was it difficult to make? Very.


#10

That method’s more costly than you think. MICR toner can go above $80 dollars. With the method I used, converting the Ferric Chloride, you’ll probably spend about $20-30 dollars, not including the Oleic acid. Oleic acid’s pricey, but chances are your Chem teacher might have it stored in the back.
