Question

which is a characteristic of a homogeneous mixture that is a liquid?
○ it exhibits the tyndall effect.
○ brownian motion is not visible in it.
○ it cannot be separated using filtration.
○ it has at least two phases.

Explanation:

1. Analyze each option:

• Option 1: The Tyndall effect is shown by colloids, not homogeneous liquid mixtures (solutions). So this is incorrect.
• Option 2: Brownian motion is visible in colloids. Homogeneous liquid mixtures (solutions) have particles too small for Brownian motion to be visible, but this is not a defining characteristic of being a homogeneous liquid mixture.
• Option 3: Homogeneous liquid mixtures (solutions) have particles that are too small to be filtered out, so they cannot be separated by filtration. This is a key characteristic.
• Option 4: Homogeneous mixtures have only one phase, while heterogeneous mixtures have at least two phases. So this is incorrect.

Answer:

It cannot be separated using filtration.
