Why do collidal solutions exhibit Tyndall effect?

Text Solution

**Step-by-Step Solution:** 1. **Understanding the Tyndall Effect**: The Tyndall effect is the scattering of light by particles in a colloid or particles in a very fine suspension. It is named after the scientist John Tyndall who first described it. 2. **Colloidal Particles**: Colloidal solutions contain dispersed particles that are larger than molecules but smaller than what can be seen with the naked eye. These particles are typically in the size range of 1 nm to 1 µm. 3. **Scattering of Light**: When a beam of light passes through a colloidal solution, the light interacts with the colloidal particles. The particles absorb some of the light and scatter the rest in different directions. This scattering is what makes the path of the light beam visible. ...

Assertion: Colloidal solution exhibit Tyndall effect while true solution particles. Reason: Because the size of the colloidal particles is large enough to scatter light as compared to size of the true solution particles.
