Question

Which of the following solutions does not show Tyndall effect ?

• A. Milk
• B. Starch solution
• C. Ink
• D. Sugar solution

Answer 1

The correct option is D Sugar solution

Sugar solution does not show Tyndall effect
The Tyndall effect is usually given as a definitive test to distinguish between a true solution and a colloid. The Tyndall effect involves the scattering of a beam of light as the light passes through a medium having particles of colloidal size. Since particles such as molecules of sugar or sodium ions or chloride ions in solution are too small to scatter light, a beam of light passing through such a solution is not scattered
