Answer 1

Answer:

i) Sand in water

$\orange{\bigstar}\:\:{\underline{\boxed{\bf\red{Brief\:Explanation}}}}$

A key characteristic of a suspension is that the solid particles will settle and separate over time if left alone. An example of a suspension is a mixture of water and sand. When mixed up, the sand will disperse throughout the water. If left alone, the sand will settle to the bottom.

Answer 2

ii. Sand in water is an example of a suspension.

Explanation:

• Suspension: A heterogeneous mixture in which solute particles do not dissolve but remain suspended; particles can be seen with the naked eye; it scatters a beam of light; particles can be isolated from the mixture by filtering.
• Sand either hangs in the water or creates a layer at the bottom of the container when added to water. As a result, sand is a non-soluble substance in water. By filtering the combination, it is simple to separate sand and water.
• A suspension solution is one in which the solute particles (sand) settle instead of being dissolved.
