Q. Explain Tyndall effect and Brownian movement with a suitable diagram.

Q.

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 ?

(b) What are the mixtures like B known as ?

(c) What are the mixtures like C known as ?

(d) Name the phenomenon exhibited by A and B which occurs on passing a beam of light through them

(e) Name one mixture each which is like (i) A (ii) B, and (iii) C.
