Answer 1

The question asks us to identify which solution exhibits the Tyndall effect. To answer this, let's first understand what the Tyndall effect is.

Tyndall Effect: The Tyndall effect refers to the scattering of light as it passes through a colloid. A colloid is a mixture where one substance is evenly dispersed in another. This scattering is visible when the light beam passes through the colloid, and it causes the path of the light to be visible.

To determine which option exhibits the Tyndall effect, we need to identify which solution forms a colloidal mixture:

NaCl solution: When NaCl dissolves in water, it forms a true solution with ions completely dissociated and evenly distributed. It does not exhibit the Tyndall effect as the particles are too small to scatter light.
Glucose solution: Glucose in water also forms a true solution with molecules evenly distributed. Similar to NaCl, it shows no Tyndall effect.
Starch solution: A starch solution is a colloidal solution because starch particles are larger and irregular, allowing light to scatter. Thus, it exhibits the Tyndall effect.
Urea solution: Similar to NaCl and glucose, urea forms a true solution in water and does not show the Tyndall effect.

Based on the above analysis, the correct answer is that the Tyndall effect is exhibited by the starch solution. This is because starch particles are large enough to scatter light, unlike the other options listed, which form true solutions with particles too small to cause scattering.
