Colloid seems ..................... and the solute particles are ..................... to eyes.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question is asking us to fill in two blanks related to the properties of colloids. The first blank describes how colloids appear, and the second blank describes the visibility of solute particles in a colloid.

2. **Identifying Colloids**: Colloids are mixtures where very small particles of one substance are dispersed throughout another substance. Common examples include milk, butter, smoke, and cheese.

3. **Describing the Appearance of Colloids**: Colloids are known for their cloudy appearance. This cloudiness is due to the scattering of light by the dispersed particles within the mixture.

4. **Visibility of Solute Particles**: The solute particles in a colloid are typically very small and cannot be seen with the naked eye. They are dispersed throughout the medium but do not settle out like larger particles in a suspension.

5. **Filling in the Blanks**: Based on the above understanding:
- For the first blank, we can fill in "cloudy" to describe the appearance of colloids.
- For the second blank, we can fill in "not visible" to describe the visibility of the solute particles.

6. **Final Sentence**: By filling in the blanks, the completed sentence reads: "Colloid seems cloudy and the solute particles are not visible to eyes."
