Question

which of the following substances will show tyndall effect? (a) salt solution (b) milk (c) copper sulphate solution (d) starch solution​

Answer 1

Answer:

b .....................

Answer 2

The substances that will show tyndall effect are milk and starch.

• Tyndall effect is light scattering by particles in a colloid or in a very fine suspension.
• Both of them will show tyndall.
• The Tyndall effect is shown by a colloidal solution and suspension.

Salt solution and copper sulphate solutions are true solutions. Therefore will not show this effect.

Here milk and starch solutions are colloid therefore milk and the starch solutions will show the Tyndall effect.
