For Paint
-
Is the mixture homogeneous or heterogeneous?
Heterogeneous. -
Is it a solution, suspension, or colloid?
Suspension. -
Explain your classification.
Paint typically contains solid pigments suspended in a liquid medium, and the particles can settle when left undisturbed, indicating a suspension. The presence of these visible particles means that paint does not achieve a uniform composition throughout.
For Orange Juice
-
Is the mixture homogeneous or heterogeneous?
Heterogeneous. -
Is it a solution, suspension, or colloid?
Suspension. -
Explain your classification.
Orange juice often contains pulp and other solid particles that do not dissolve completely in the liquid, making it a suspension. Because you can see these particles and they can settle over time, it is classified as heterogeneous.
For Soda
-
Is the mixture homogeneous or heterogeneous?
Homogeneous. -
Is it a solution, suspension, or colloid?
Solution (specifically, a carbonated solution). -
Explain your classification.
Soda is a homogeneous mixture where sugar and carbon dioxide gas are dissolved in water, resulting in a uniform distribution of ingredients throughout the liquid. The bubbles of carbon dioxide may be visible, but they do not affect the overall uniformity of the mixture.
For Salad Dressing (Example)
-
Is the mixture homogeneous or heterogeneous?
Heterogeneous. -
Is it a solution, suspension, or colloid?
Suspension. -
Explain your classification.
Salad dressing, especially vinegar-based ones, often contain oil and various solid spices that do not fully integrate, leading to visible separation of components. This lack of uniformity indicates that it is a heterogeneous mixture and functions as a suspension.
