Question: Write difference between homogeneous and heterogeneous mixture....
Write difference between homogeneous and heterogeneous mixture.
Solution
Mixtures can be formed when two or more substances, elements or compounds mix together without participating in a chemical change. These substances need not necessarily mix in a definite ratio to form a mixture.
Complete answer:
Homogeneous Mixture are those types of mixtures in which components mixed are uniformly distributed throughout the mixture. In other words,we can say that “they are uniform throughout”. We can observe only one phase of matter in a homogeneous mixture.
Important points regarding such type of mixtures are:
-Particles are uniformly distributed.
-We can’t judge a mixture is a homogeneous mixture by just seeing it
-Homogeneous mixtures are also named as solutions
-They have Uniform composition
-Example of such type of mixtures are rainwater, vinegar, etc.
Heterogeneous Mixture is a type of mixture in which all the components are completely mixed and all the particles can be seen under a microscope. We can easily identify the components and more than one phase can be seen by naked eyes.
Important points regarding this type of mixtures are :
-Particles in it are non uniformly distributed.
-We can judge if a mixture is heterogeneous , by just seeing it.
-They have non-uniform composition
-Example of such type of mixtures are seawater, pizza, etc.
A homogeneous catalyst is used in the same phase as all the reactants will be in the same state of matter as the other reactants. Heterogeneous catalysts can be used in a different phase from the reactants and it can be in a different matter of state from the reactants.
Difference between Homogeneous and Heterogeneous Mixture
| Homogeneous mixtures | Heterogeneous mixtures |
|---|---|
| -They have a uniform composition | -They have a non-uniform composition |
| -There is only one phase | -There are two or more phases possible |
| -They can’t be physically separated out | -They can be physically separated out |
| -‘homo’ in homogeneous means the same | -‘hetero’ in heterogeneous means different |
| -Example :-a mixture of alcohol and water,etc | -Example:- a mixture of sodium chloride and sand,etc |
Note:
Particles are uniformly distributed in homogeneous mixtures. Particles are non uniformly distributed in non homogeneous mixtures. We can judge a heterogeneous mixture by just seeing it, which is not possible in case of homogeneous mixtures.
