Concept explainers
Classify each of the following mixtures as homogeneous or heterogeneous. Briefly justify your answer.
- a. a bowl of vegetable soup
- b. mouthwash
- c. an unopened can of cola
- d. a dinner salad
a.
To determine:
The categorization of the given bowl of vegetable soup as homogenous or heterogeneous mixture.
Introduction:
A mixture in which the composition of its constituent is uniform and indistinguishable throughout the solution is called homogenous mixture.
A mixture in which the composition of its constituent is not uniform but distinguishable throughout the solution is called heterogeneous mixture.
Explanation of Solution
A mixture in which the composition of its constituent is uniform and indistinguishable throughout the solution is called homogenous mixture.
A mixture in which the composition of its constituent is not uniform but distinguishable throughout the solution is called heterogeneous mixture.
A bowl of vegetable soup is a heterogeneous mixture as the vegetable chunks are not uniformly distributed in the vegetable soup. Every spoon contains different amount of vegetables and other components of the soup.
b.
To determine:
The categorization of the mouthwash as homogenous or heterogeneous mixture.
Introduction:
A mixture in which the composition of its constituent is uniform and indistinguishable throughout the solution is called homogenous mixture.
A mixture in which the composition of its constituent is not uniform but distinguishable throughout the solution is called heterogeneous mixture.
Explanation of Solution
A mixture in which the composition of its constituent is uniform and indistinguishable throughout the solution is called homogenous mixture.
A mixture in which the composition of its constituent is not uniform but distinguishable throughout the solution is called heterogeneous mixture.
Mouthwash is a homogeneous mixture as its composition is uniform throughout the solution.
c.
To determine:
The categorization of the given unopened can of cola as homogenous or heterogeneous mixture.
Introduction:
A mixture in which the composition of its constituent is uniform and indistinguishable throughout the solution is called homogenous mixture.
A mixture in which the composition of its constituent is not uniform but distinguishable throughout the solution is called heterogeneous mixture.
Explanation of Solution
A mixture in which the composition of its constituent is uniform and indistinguishable throughout the solution is called homogenous mixture.
A mixture in which the composition of its constituent is not uniform but distinguishable throughout the solution is called heterogeneous mixture.
An unopened can of coca cola is homogenous mixture as its particles are indistinguishable and its composition is uniform throughout solution.
d.
To determine:
The categorization of the given dinner salad as homogenous or heterogeneous mixture.
Introduction:
A mixture in which the composition of its constituent is uniform and indistinguishable throughout the solution is called homogenous mixture.
A mixture in which the composition of its constituent is not uniform but distinguishable throughout the solution is called heterogeneous mixture.
Explanation of Solution
A mixture in which the composition of its constituent is uniform and indistinguishable throughout the solution is called homogenous mixture.
A mixture in which the composition of its constituent is not uniform but distinguishable throughout the solution is called heterogeneous mixture.
A dinner salad is a heterogeneous mixture as the components of salad are distinguishable.
