  • What kind of magnet it is? Would this work with a magnet you buy at dollarama?

  • @nicxtrem21 I am using a small neodymium magnet here, it works with regular magnets but they are weaker and so they pull less.

    I also put the magnet into a plastic baggie to make it easier to get the filings off of the magnet.

  • @nicxtrem21by the way i use a big magnet te ones you take of the speakers

  • hi...that was cool experiment. is that same like to separate wax from salt and sand using trichlor liquid? I've got task on this....but I try to do like evaporate salt, sand and wax mixtures together after that filtering again the mixtures with trichor and I figure out that salt and sand insoluble with trichlor liquid only wax can go through the liquid. am i right? 

  • @canchofurz I'm not sure I totally follow the procedure you are describing, but wax should be soluble in trichlor liquid while salt will not be and sand is not really soluble in anything.

  • hey im doin this in my next chemistry class.....how do u separate kerosine from water

  • You should be able to separate them because they have different densities and will not mix with one another,a separatory funnel helps, but isn't necessary. You could also possibly burn off the kerosene, but it isn't the safest or a good method if you need to recover the original amount.

  • ok...so i use a sepatory funnel....and how do i pour the kerosine out?

    since the water will come out too

  • A separatory funnel has a valve at the bottom, you just visually watch for one liquid to move out and stop the valve before the second liquid comes out.

  • how do u burn the kerosine????

  • A flame or heat.

  • How would you separate the sand from the salt, but still having the salt in a solid state, not mixed with water?

  • You might be able to separate them using density, but beyond that I don't know of a way. I separate them using water and then evaporate the water which leaves behind the salt.

  • hey, do you know how i would seperate sand, salt, chalk and iron filings from water? i dont understand how to seperate the chalk and sand as they are both suspensions! could someone please help me?

  • I can think of a way to get them separated, but the chalk does not remain a powder. Start out removing iron from everything with a magnet [as in this video].

    Add water to dissolve salt and sand will sink. It is possible that chalk will float, but it probably is a suspension, as you say.

    Filter let it dry to get the salt.

    Add a weak acid to sand and chalk from the filter (like vinegar) to dissolve the chalk (but this releases CO2 changing the chemical composition of the chalk).

  • Water.

    Styrofoam will float, sand will sink, and salt will dissolve (with stirring).

    If you actually have to do it then, skim off the Styrofoam filter the water off the sand. Allow the water to evaporate or force it with heat.

    It sounds like I am answering a homework question and I should let you think of the answer on your own, but I've been looking for an alternative to the plastic beads I use which don't always float properly and hadn't thought of Styrofoam yet, so thanks.

  • whoa.. i'm also doin this for my class but we have to figure out on wat to do next

  • What are you trying to separate next?

  • i am doing this in my science classssss

  • Cheers.
