Question
In the picture below, a beam of light is passing through the solution present in beaker A and beaker B. What types of solutions are present in beaker A and beaker B, respectively?
- Colloid and suspension
- Solution and colloid
- Suspension and solution
- Solution and alloy
Hint:
Solution and colloid
The correct answer is: Solution and colloid
- When a beam of light is passed through a colloidal solution, light scattering is detected. This is referred to as the Tyndall effect. This light scattering highlights the beam's course in the colloidal fluid.
- Particles in solutions are too small to scatter a beam of light. Hence, the path of light is not visible when it passes through them.
