Understanding Colloidal Solutions
A colloidal solution is a mixture where tiny particles are dispersed throughout a medium but do not settle out or separate like in a suspension.
Examples of Different Solutions
- Salt in Water: This is a true solution where salt completely dissolves in water, forming a homogeneous mixture.
- Muddy Water: This is a suspension where larger particles of dirt are mixed with water, and they can settle out if left undisturbed.
- Milk: This is the correct example of a colloidal solution. Milk contains tiny fat globules dispersed in water, which do not settle out and give it a uniform appearance.
- Sand in Water: This is also a suspension since sand particles are larger and will settle down if allowed to sit.
Characteristics of Colloids
- Particle Size: Colloids have particle sizes that range between 1 nanometer and 1 micrometer.
- Tyndall Effect: Colloidal solutions scatter light, which is known as the Tyndall effect. This is why milk appears opaque.
- Stability: Colloids remain stable over time, as the dispersed particles do not settle out.
Conclusion
Given these characteristics, the correct answer is option 'C' (Milk), as it is the only example provided that fits the definition of a colloidal solution.
