Answer 2

Answer:

A) salt solution And C) copper sulphate

Explanation:

Tyndall effect is shown by those mixtures which are colloids. This is because colloids have suspension of small particles, from 1 – 1000 nanometres in size which can scatter light falling on them, a phenomenon called as Tyndall effect.

In the above question, only b) milk and d) starch solution show Tyndall effect as they are colloids. a) salt solution and c) copper sulphate solution are solutions and therefore don’t show Tyndall effect.
