Explain why a suspension is considered a heterogeneous mixture.
Suspension is a heterogeneous mixture because ti has multiples distinguishable parts.
A suspension is considered a heterogeneous mixture because it consists of particles that are distributed unevenly throughout the mixture. Heterogeneous mixtures are those in which the components can be seen separately and do not blend uniformly. In the case of a suspension, the particles of one substance are dispersed in another substance, forming a mixture where the particles settle down over time when left undisturbed.
To understand why a suspension is considered heterogeneous, you can perform a simple experiment.
First, take a clear glass of water and add some sand to it. At the beginning, the sand particles will be dispersed throughout the water, giving the mixture a cloudy appearance. Now, if you observe the mixture after some time, you will notice that the sand particles settle down at the bottom of the glass.
This settling of particles in a suspension is due to gravity. Gravity acts on the particles, causing them to separate and settle out. As a result, the particles become visible, and the mixture appears heterogeneous.
Another example of a suspension is milk. Milk is a mixture of water, fats, proteins, and other substances. If you leave a glass of milk undisturbed, you will observe that the fat globules rise to the top and form a layer of cream. This separation of the components further confirms the heterogeneous nature of a suspension.
In summary, a suspension is considered a heterogeneous mixture because its components, in the form of solid particles or globules, do not blend uniformly and settle out over time.
