Answer 1

Answer:

ii)Starch solution will show the effect of tyndall solution.

Answer 2

Explanation:

• Ferrous sulphate - It is a true solution and hence it won't show Tyndall effect . Tyndall effect is shown by those mixtures which are colloids.
• Starch solution - It is a colloid and therefore, it will show Tyndall effect.

$\bf \large \underline \green{extra \: information}$

• The Tyndall effect is the scattering of light as a light beam passes through a colloid.

• The individual suspension particles scatter and reflect light, making the beam visible.

• The Tyndall effect was first described by 19th-century physicist John Tyndall.
