Particles of suspension do not scatter a beam of light.
Understanding Suspension Properties
The question asks to identify the statement that is INCORRECT about the properties of a 'suspension'. Let's examine each given property:
- Suspension is a heterogeneous mixture. This statement is correct. Suspensions have a non-uniform composition where particles are dispersed but not dissolved.
- Particles of suspension are visible to the naked eye. This statement is correct. The particle size in a suspension is typically large enough (e.g., > 1000 nm) to be seen without magnification.
- Particles of suspension do not scatter a beam of light. This statement is incorrect. Particles in a suspension are sufficiently large to scatter light, making a beam passing through it visible (Tyndall effect). This is a characteristic property of suspensions.
- Particles of suspension can be separated from the mixtures by the process of filtration. This statement is correct. The large size of suspension particles allows them to be separated from the liquid or gas medium using a filter.
Conclusion on Incorrect Property
The property listed which is INCORRECT for a suspension is the claim that its particles do not scatter a beam of light. In reality, suspensions exhibit light scattering due to the size of their dispersed particles.
