1. Salt
2. Sand
3. Iron Fillings

how can i separate these three substances so that all three come out in three diferent piles of differnet substances.

Answer 1

Use a magnet to remove the iron filings. Then add water to dissolve the salt and remove it.

Answer 2

Here is my guess about how to do it: First use a magnet to pick out the iron filings, then put water into the remaining stuff. The salt will dissolve in the water leaving only the sand. Later you can evaporate the water in a pan to get your salt back.

Answer 3

First use a magnet to remove the Iron fillings as there magnetic.

Secondly add water until the salt is dissolved and then filter as the sand will not dissolve in the water.

Lastly boil the water off and salt should rename.

Answer 4

we separate the 2 sand and ,the metal .we pout all the substances in the water at the top is the sand,a the bottom is iron,and the water is the mealed SALT .first you remove the sand, then Wat is left is the iron fillings,then you knead to supered the water.you pouting the water,to boil,after the water evaporate,what is left is the salt and all are separate.
magnet is not to be yous because ,if the iron ,stainless or aluminum or led , magnet can't be yous.

Answer 5

for the iron fillings, use a magnet. for the salt and sand im not sure... im thinking something with a filter or water. i know that sand would fall to the bottom of a glass of water and the salt would desolve. then you would evaporate the water after taking out the sand so that you're only left with the salt. but, i think that's a little too complicated. i tried!

Answer 6

very easily at least for the iron fillings...a magnet will do the trick..as for the salt and sand....mix the salt and sand in water then put it through a paper filter....the sand will remain in the paper filter while the salt water goes through....then just boil away the water and presto...u have ur salt and everything filtered!

trust me we did this before in chem

Answer 7

thats gunna be hard because sand contains salt..... but i think the only way to honestly separate substances in a lab expirience is fire..... or use the metal thing that swirls in a circle

Answer 8

i in my opinion can't arise with a nitrate compound that may not soluble in water, so it exists as ions. there may be some unusual ones, yet not the common compounds. yet particular components basically scream out at being insoluble compounds, and lead compounds (different than for lead nitrate) are going to be insoluble in water.

Answer 9

A magnet and
Heat IF they are suspended in H2O

Answer 10

heating or cooling a mixture can help you to seperate the different components. you should google this...you'd find the answer. but when I took chem, that's what we did.
