In the classification of matter, muddy water is best described as which type of mixture?

• A. Colloid
• B. Pure substance
• C. Suspension
• D. Solution

Answer: (C)

Verified step by step guidance

1. Recall the main types of mixtures: solutions, colloids, and suspensions. Each differs in particle size and how particles behave in the mixture.
2. Understand that a solution is a homogeneous mixture with particles at the molecular or ionic level, which do not settle out over time.
3. Know that a colloid has intermediate particle size, where particles are dispersed but do not settle quickly and can scatter light (Tyndall effect).
4. Recognize that a suspension contains larger particles that are dispersed but will eventually settle out due to gravity if left undisturbed.
5. Since muddy water contains visible particles that settle over time, classify it as a suspension, which is a heterogeneous mixture with large particles.
