Select the correct option with respect to the following statements.
Statement-1: Suspension is a homogeneous mixture.
Statement-2: The particles of a suspension can be seen by the naked eye.
Statement-3: The solute particles settle down when a suspension is left undisturbed, that is, a suspension is unstable.
Suspension Characteristics Explained
This solution analyzes three statements about suspensions to identify the correct ones.
Statement 1: Homogeneous Mixture?
Incorrect. A suspension is fundamentally a heterogeneous mixture. The components are not uniformly distributed throughout the mixture.
Statement 2: Visible Particles?
Correct. Particles in a suspension are relatively large, often exceeding 1000 nanometers. This size allows them to be observed using the naked eye.
Statement 3: Unstable Mixture?
Correct. Due to their size and the effect of gravity, particles in a suspension tend to settle down when the mixture is left undisturbed. This settling behaviour confirms that suspensions are unstable.
Correct Statements Identification
Based on the analysis:
- Statement 1 is incorrect.
- Statement 2 is correct.
- Statement 3 is correct.
Therefore, the option stating that Statement 2 and Statement 3 are correct is the accurate choice.
