Question

what is the method used to separate saw dust from the mixture of iron fillings, sand and copper (II) sulphate?

Answer 1

First dissolve the iron fillings , copper sulfate and saw dust in water ,
when you do this copper sulfate get soluble in water and iron fillings and saw dust are insoluble in water, then you filter it
after filtration u have saw dust and iron fillings as a mixture on the filter paper right
to this mixture you add the magnet it attracts all the iron fillings and whatever not attracted by the iron fillings remained is saw dust :)

i did this experiment act 2 weeks ago, but i forgot how separated the saw dusts. well, this is how how we separated them.

Answer 12

1- we separated iron fillings using magnet
2- then used filtration to filtrate sand
3- then we did evaporation method to evaporate the water, leaving small crystals of copper sulphate

Answer 13

ok fine if you know why did you ask then ??

Answer 14

how to separate saw dust

Answer 15

thats the missing part

Answer 16

those three mixture again you dissolve in a beaker containing water and
the saw dust will be on the surface of water undissolved , iron fillings and sand being haveir will be undissolved at the bottom of the beaker, then slowly filter the water surface layer containing the saw dust
and at the bottom of water will be ur sand and the iron fillings
you evaporate the water you will have these two mix you put magnet into this only Fe will be attracted and the rest is sand
