The _____ is used to identify a mixture as a colloid. tyndall effect particle effect motion effect doppler effect

Answer 1

The answer is the Tyndall Effect.

Step-by-step explanation:

The Tyndall effect is a physical phenomenon present in suspensions, where the existence of colloidal particles is present.

Colloidal particles are invisible particles to the naked eye due to their small size, and have the property of reflecting or refracting the light that reaches them. These particles can be solid, liquid or gaseous. The medium where they are suspended can also be in any of the three phases.

When a beam of light passes through a colloidal suspension, an emission of light occurs that reveals the particles. On the other hand, solutions that do not have particles of this type are transparent, because there is nothing to disperse the light that enters. Then the particles that are dissolved in it are not macroscopically or microscopically distinguished (the light path is not observed). Thanks to this difference, colloidal suspensions can be distinguished.

Answer 2

The Tyndall effect is used to identify a mixture as a colloid.
According to a chemistry book, the Tyndall effect is "the effect of light scattering in colloidal dispersion, while showing no light in a true solution." And a colloid is a solution that has a lot of particles.
