๐ฌ Think about it
- We have separated homogeneous mixtures in three different ways.
- But in a heterogeneous mixture the parts do not even mix properly — oil and water, sand and water.
- Does that make separating them easier, or harder?
What is different about heterogeneous mixtures?
- In a heterogeneous mixture the solute mixes non-uniformly with the solvent.
- Oil and water, sand and water, iron filings and sulfur — in all of these the two parts never mix completely.
- So the methods we use here are quite different from the ones in 5.3.
