Which of the following mixture types can be filtered to remove the solute?

• A. Suspension
• B. Solution
• C. Colloid
• D. Alloy

Answer: (A)

Verified step by step guidance

1. Understand the nature of each mixture type: Solution, Colloid, Suspension, and Alloy. A solution is a homogeneous mixture where the solute particles are dissolved at the molecular or ionic level, making them too small to be filtered out.
2. Recognize that a colloid is a mixture where particles are intermediate in size between those in solutions and suspensions. These particles do not settle out and are generally too small to be removed by ordinary filtration.
3. Identify that a suspension consists of larger particles that are dispersed throughout a liquid but are not dissolved. These particles are large enough to be trapped by a filter, allowing the solute to be separated from the solvent.
4. Note that an alloy is a solid solution or mixture of metals, where the components are mixed at the atomic level, making filtration impossible.
5. Conclude that only suspensions can be filtered to remove the solute because their particles are large enough to be separated by filtration, unlike solutions, colloids, or alloys.
