    Question on Ferrofluid

    Couple of other questions. 1) This is just to make sure that I answered this question correctly, but in the ferrofluid, there are two ions of Fe 3+ and one ion of Fe 2+ present, correct? 2) Having a bit of difficulty understanding this question: *You prepared aqueous ferrofluid, but the...

    Question on Ferrofluid

    Wow, I feel stupid. Aqueous ferrofluid would result in rust, thereby making the ferrofluid inefficient. I suppose not. A magnet could be placed in the area of the region outside of the body that the ferrofluid needs to enter, just depends on how strong the attraction would be in order to not...

    Question on Ferrofluid

    Are you asking how iron reacts with different ions in general or something different? I'm apologize for not understanding the question, but I'm quite awful when it comes to chemistry. To localize the delivery, wouldn't you need an actual magnetic piece or magnetic attraction for the...

    Question on Ferrofluid

    I recently did a lab report on ferrofluid for chemistry and am having difficulty with some questions. I was wondering if I could get some help. *Are there advantages to an oil-based ferrofluid compared to an aqueous ferrofluid? *Researchers have explored ways to attach medications to...
