How do you separate the components of Iodine, salt, and sand?

Question

aaronq · Answer

think about how you could exploit their physical or chemical characteristics.

HINTS: compare boiling points (use distillation) and compare solubility in water

anonymous · Answer

So I know with salt and sand I will dissolve the sample in water and then filter out the sand.... with the iodine I should do that first? heat it?

aaronq · Answer

i would heat the mixture to get rid of the iodine, then put the sample in water - only salt is soluble in water, sand is not.

with this will I be able to tell the percent of the components?

aaronq · Answer

well you'd have to collect everything and someone measure their amounts, it's easy for sand and salt. But for iodine, you'd have to collect it as a gas then condense it back to a liquid (or solid) then find it's weight (taking it's density into account if it's a liquid).

With this information given, am I able to get percents?

anonymous · Answer

I think from you last response I am working an answer!!! Thanks so much for your help

aaronq · Answer

you wont be able to get the percent composition in the mixture since you dont have any values. No problem !
