Question

Which of the following will show Tyndall effect ?
(a) Starch Solution
(b) Sodium chloride solution
(c) Copper sulphate solution
(d) Sugar solution .

Give reasons for your answer !!

Answer 1

Tyndall effect is the scattering of light by the particles of the mixture when passed through it. Tyndall effect is a characteristic property of colloids. Here, Starch solution is a colloidal solution. Hence, it shows tyndall effect.

Others like copper sulphate, sugar solution,sodium chloride are true solutions, hence don't exhibit tyndall effect

Therefore, Starch solution shows tyndall effect

Answer 2
