Question

Which does not show the Tyndall effect?

Options

• Emulsion

• Blood

• Milk

• Sugar solution

Answer 1

Sugar solution

Explanation:

The Tyndall effect is the scattering of light by colloidal particles. Emulsion, blood, and milk are colloidal systems and show the Tyndall effect. In contrast, a sugar solution is a true solution with particles too small to scatter light, so it does not show the Tyndall effect.
