How do you know if its homogenous or heterogenous mixture?
Answer:
If you can easily see or separate the ingredients, it is a heterogenous mixture. If the ingredients are finely mixed and it is difficult to separate, it is a homogenous mixture.
A solution of salt or sugar in water will be a homogenous mixture.
A mixture of sand and pebbles is a heterogenous mixture.
A basket containing apples and oranges is a heterogenous mixture (you can clearly see and separate the two).
A mixed fruit milkshake is a homogenous mixture.
Do you have an equation...? If you've got an equation, then see if the states of the elements and/or compounds are the same. For example, if all the reactants and products are gases, then it's a homogeneous mixture.
Na (s) + Cl (s) --> NaCl (s)
Since all the elements are solids, then it's homogeneous.
If all the reactants and products are in various kinds of states (one's liquid, one's solid, the rest are gases... something like that), then it's a heterogeneous mixture. The reason why should be pretty obvious. If you don't have the equation, then I can't help you.
Look at it. If it is clear, or even in composition, then it is homogenous. All solutions are homogenous mixtures. However, if it appears grainy, has layers, or is otherwise uneven in composition, it is heterogenous.
what? do you realize that homo is of the same genus and hetero is of different genus? what is your question again?
Homogenous means it's all the same. So if you took a knife and cut the material in to a thousand pieces, or a billion, each piece would be exactly the same. You can't make that claim about cake or a sandwich, but you can do that with steel or jello. Heterogenous mixtures are different through out. A piece of wood can be cut in to many pieces, some pieces may have knows and bark while others might not - this is heterogenous. This is not a simple task though - what about milk? Milk is a suspension of fat and protein particles in water/whey. Milk looks very homogenous, but under a microscope it may appear to look like ice-bergs in the sea. It depends on the scope of the analysis and the desired outcome
hold the test tube against a lamp and try to see through it. then do that again after 5min, without shaking. If the mixture becomes more transparent, and/or a pile of debris settles at the bottom, the mixture is heterogenous.
