DIFFERENTIATE BETWEEN :- (a) COMPOUNDS AND MIXTURE (b) HOMOGENEOUS AND HETEROGENEOUS (c) SUSPENSIONS AND SOLUTIONS
Solution:
(a) Difference between compounds and mixture.
(b) Difference between homogeneous and heterogeneous mixture.
(c) Difference between suspensions and solutions mixture.
(a) Difference between compounds and mixture.
Mixture | Compound |
It is obtained by the physical combination of either element, compounds, or both. | It is obtained by the chemical combination of more than one element. |
The composition of elements present in a mixture is not fixed. | The composition of elements present in a compound is fixed. |
It shows the properties of all its constituents. | It may or may not show the properties of its constituent elements. |
Its constituents can be separated using physical methods. | Its constituents can be separated by using only chemical and electrochemical methods |
(b) Difference between homogeneous and heterogeneous mixture.
Homogeneous mixture | Heterogeneous mixture |
A homogeneous mixture has a uniform composition throughout its mass. | A heterogeneous mixture has a non-uniform composition. |
A homogeneous mixture does not contain physically distinct parts. | A heterogeneous mixture contains physically distinct parts. |
Homogeneous mixtures form solutions. | Heterogeneous mixtures form colloids or suspensions. |
Example: A mixture of alcohol and water is homogeneous. | Example: A mixture of sodium chloride and sand is heterogeneous. |
(c) Difference between suspensions and solutions mixture.
Suspensions | Solutions |
A suspension has bigger particle sizes and so it may look cloudy or murky. | A solution is a mixture of ions or molecules (very, very small). Solutions are transparent, meaning that you can see through them. |
They are heterogeneous mixtures. | They are homogeneous mixtures. |
Example: Chalk powder (stirred in water or solvent - water), | Example: Soda powder (stirred in water or solvent - water) |
