A mixture of sand particles and water is agitated perfectly for some time, so that the distribution of sand become uniform at every point. Identify correct statement for such condition.
It is the example of homogeneous mixture
It is the mixture of two pure elements
It is the mixture of one pure element
It is the example of heterogeneous mixture
Answers
The correct statement for such a condition is:
It is the example of a homogeneous mixture.
- A homogeneous mixture is uniform throughout.
- It is given that the distribution of sand particles in water becomes uniform at every point after the perfect agitation.
- Since the distribution is uniform at every point, so it is an example of a homogeneous mixture.
D) It is the example of heterogeneous mixture.
Explanation:
A mixture of sand particles and water are agitated perfectly for sometime, such that the distribution of sand become uniform at every point. As sand is solid, it does not dissolve in water, forming 2 different phases present in the mixture of sand and water. Even in such a mixture of uniform distribution, you can visibly find sand particles, though uniform, swirling in water and it is easy to separate the two components using an appropriate filter. So it is an heterogeneous mixture.
Option D is the answer.
