Question

Match the following:

• A. 1-S, 2-R, 3-Q, 4-P
• B. 1-Q, 2-S, 3-R, 4-P
• C. 1-S, 2-Q, 3-R, 4-P
• D. 1-R, 2-S, 3-Q, 4-P

Hint:

Colloids scatter (Tyndall); True solutions don't.

Answer 1

The Correct Option is A

Step 1: Concept
This question relates to the optical properties of colloidal systems versus true solutions.

Step 2: Meaning
The Tyndall effect is the scattering of light by colloidal particles.

Step 3: Analysis
1-S: Tyndall effect is light scattering. 2-R: Ultra microscopes utilize scattering phenomena to view particles. 3-Q: Visible light allows for the observation of particles. 4-P: True solutions do not show the Tyndall effect because particles are too small.

Step 4: Conclusion
Matching the properties correctly results in option (a). Final Answer: (a)
