Is salt and iron filings heterogeneous?
Salt water solution is a homogeneous mixture, for example, but salt mixed with sand is a heterogeneous mixture. For example, if iron filings and sulfur powder are mixed together, they constitute a chemical mixture.
Was the mixture of salt sand and iron filings homogeneous or heterogeneous?
heterogeneous mixture
Mixture of sand and iron filings is heterogeneous mixture.
What kind of mixture is salt and iron filings?
Wrap a magnet in plastic lunch wrap and move it through the mixture of the three solids. The iron filings will stick to the magnet. The filings can be removed by unwrapping the plastic from the magnet carefully! Mix the remaining salt and sand in water and stir….

Is iron filings a heterogeneous or homogeneous?
Material
| Material | Pure Substance or Mixture | Element, Compound, Homogeneous, Heterogeneous |

| iron filings (Fe) | Pure Substance | Element |
| limestone (CaCO3) | Pure Substance | Element |
| orange juice (w/pulp) | Mixture | Heterogeneous |
| Pacific Ocean | Mixture | Heterogeneous |
Why is salt and sand a heterogeneous mixture?
Salt is soluble in water, which would give a homogeneous mixture. But, when you add sand, which is insoluble, you will have a mixture of two different phases, a solid and a liquid, therefore this is a heterogenous mixture.
Is salt and iron filings can be separated?
Of course you could do the separation chemically. Dissolve the salt up in water, pass thru a filter, wash the iron filings with ethanol, which would encourage the salt to precipitate from solution.
How do you separate iron filings and salt in one container?
The salt dissolves, the other solids do not. Using the fact that the iron is magnetic, the magnet can be used to separate the iron fillings from the mixture by moving teh magnet around in the container. Keeping the magnet in a plastic bag makes it easy to separate the filings from the magnet when you pull it out.
Is the iron and sand mixture homogeneous or heterogeneous?
A heterogeneous mixture is simply any mixture that is not uniform in composition. If we take many parts of this mixture, they will have different amounts of iron fillings and sand (i.e. b on uniform composition). Hence it is a heterogeneous mixture. Is salt iron and sand a heterogeneous mixture?
Can a homogeneous mixture be a pure substance?
(Homogeneous mixtures can sometimes be mistaken for pure substances because of their uniform appearance.) Salt water solution is a homogeneous mixture, for example, but salt mixed with sand is a heterogeneous mixture. For example, if iron filings and sulfur powder are mixed together, they constitute a chemical mixture.
Which is the best description of a heterogeneous mixture?
A heterogeneous mixture is blurry, turbid, like when you pour some milk into the above coffee. Gases form only homogeneous mixtures. Solids, when mixed in the solid state even if they were very finely ground, form only heterogeneous mixtures, since you could recognize the different grains under a microscope.
Why is iron sulfide a compound and not a mixture?
Iron Sulfide is a compound and not a mixture because when Iron and Sulphur are mixed and heated then they combine chemically in order to form a new substance named Iron Sulfide and after its formation these can not be differentiated as individual elements and in each portion of the Iron Sulfide the proportion of Iron …
