Which of the following does NOT describe a suspension?
A)particles are soluble
B)particles settle out over time
C)particles can block light
D)particles scatter light
A is not true.
A) particles are soluble.
To determine which of the following options does NOT describe a suspension, we need to understand the characteristics of a suspension.
A suspension is a heterogeneous mixture in which solid particles are dispersed in a liquid or gas. These solid particles are usually insoluble in the dispersing medium.
Let's analyze each option:
A) "Particles are soluble": This statement does NOT describe a suspension because in a suspension, the solid particles are usually insoluble. So, option A can be eliminated.
B) "Particles settle out over time": This statement describes a suspension because suspended particles will settle at the bottom of the container over time due to gravity.
C) "Particles can block light": This statement describes a suspension because when light passes through a suspension, the suspended particles can scatter the light, making the suspension appear cloudy or opaque.
D) "Particles scatter light": This statement describes a suspension because when light passes through a suspension, the suspended particles scatter the light in different directions, contributing to the cloudy or opaque appearance.
After analyzing all the options, we can conclude that option A) "particles are soluble" does NOT describe a suspension.
