Why only lyophobic colloids show tyndall effect?

Lyophobic colloids have particles that repel the dispersion medium, preventing them from easily mixing. This causes the particles to scatter light, which is why they exhibit the Tyndall effect. In lyophilic colloids, the particles have an affinity for the dispersion medium and do not scatter light as effectively.


Is tyndall effect observed in true solution?

No, the Tyndall effect is not observed in true solutions. True solutions contain solute particles that are smaller than the wavelength of visible light, so they do not scatter light and appear transparent. The Tyndall effect is only observed in colloids or suspensions where the particles are larger and can scatter light, making the solution appear cloudy or opaque.


What type of mixture scatters light?

Colloids are mixtures that contain small particles suspended in a medium. These particles are large enough to scatter light, causing the mixture to appear cloudy or opaque when light is shone through it.


The scattering of visible light in all directions by colloids or suspensions is?

called Tyndall effect. It occurs when light passes through a medium containing small particles that scatter the light, making the beam visible. The scattered light is mainly due to the reflection and refraction of light by the particles in the medium.


Why do colloids show the Tyndall effect?

In true solutions the solute dissolves completely in the solvent at the molecular level, meaning that the solute particles are present at their molecular size - well below the size of a particle required to exhibit light scattering dispersion (the Tyndall effect).

Which mixture scatter a beam of light that passes through them-a phenomenon called the Tyndall effect?

Colloids scatter a beam of light that passes through them, exhibiting the Tyndall effect. This is due to the particles in colloids being large enough to obstruct the path of light and scatter it in all directions, making the beam visible.

Do suspensions scatter light?

Yes, colloids scatter light. Colloids are mechanical mixtures; all mechanical mixtures scatter light. Solutions are the only mixtures that do not scatter light. The scattering of light by mixtures is known as the Tyndall effect, btw.

What is a homogeneous mixture that contains particles that scatter light?

They are called "colloids". These have large particles that are suspended in a solution.


Why do colloids produce the Tyndall effect?

Colloids produce the Tyndall effect because their particles are larger than the particles in a solution, allowing them to scatter light. When a beam of light passes through a colloid, it interacts with the dispersed particles, causing the light to become visible as a scattered beam. This scattering effect is what makes the colloid appear to be cloudy or milky when illuminated.


How tyndall effect can help you determine if a mixture is a colloid or not?

The Tyndall Effect can help determine if a mixture is a colloid by observing if the mixture scatters light. Colloids will scatter light, causing the light beam to become visible when passing through the mixture. If the mixture does not scatter light, it is likely not a colloid.

Can mixtures be classified as solutions suspensions or colloids?

Yes, mixtures can be classified as solutions, suspensions, or colloids based on the size of the particles present. Solutions have particles that are very small and do not settle out, suspensions have larger particles that eventually settle, and colloids have intermediate-sized particles that do not settle but scatter light.
