Which of the following is true for suspension? a. Suspension is a heterogeneous mixture. b. The particles of a suspension scatter a beam of light passing through it. c. The particles of a suspension can be seen by the naked eye.
Understanding Suspension Characteristics
The question asks to identify the true statements regarding suspensions. Let's analyze each statement:
Statement Analysis
-
Statement a: Suspension is a heterogeneous mixture.
This is correct. A suspension consists of solid particles dispersed in a liquid or gas, where the particles do not dissolve and remain suspended. The composition is not uniform throughout, making it a heterogeneous mixture.
-
Statement b: The particles of a suspension scatter a beam of light passing through it.
This is also correct. Due to their relatively large size, the particles in a suspension effectively scatter light that passes through it. This phenomenon is known as the Tyndall effect, which makes the light beam visible.
-
Statement c: The particles of a suspension can be seen by the naked eye.
This statement is true. The dispersed particles in a suspension are generally large enough, often exceeding 1000 nanometers, to be distinguished and observed using the naked eye.
Conclusion on Suspension Properties
Since statements a, b, and c are all accurate descriptions of a suspension's properties, the correct option must include all three.
