Do homogeneous mixture scatters a beam of light?

Open in App

Solution

The Tyndall effect distinguishes colloids from solutions. In a solution, the particles are so fine that they willnot scatter light. This is not true for a colloid. If you shine light through asolution, the beam of light will not be visible

Q. Mark the correct statement(s).
(I) The solute particles settle down when suspension is left undisturbed.
(II) Particles of a suspension scatter a beam of light passing through it and makes its path visible.

Q. The table given below shows the properties of two unknown mixtures X and Y.

\begin{matrix} Mixture & Type of Mixture & Light scattering X & Homogeneous & Does not scatter light Y & Heterogeneous & Scatters light \end{matrix}

Identify X and Y from the following.

Three mixtures A, B and C are obtained by stirring three different solids in water taken in separate beakers. When mixture A is allowed to stand for some time, then its particles settle at the bottom of the beaker. When a Beam of light is passed through mixture A in a dark room, the path of light becomes visible when observed from the side of the beaker. When mixture B is allowed to stand for a considerable time, even then its particles do not settle down. Mixture B, however, scatters the beam of light just like mixture A. The particles of mixture C do not settle down on keeping and it also does not scatter a beam of light passing through it

(a) What are the mixtures like A known as ?
