Question

which statement is incorrect about Tyndall effect? a. true solution show Tyndall effect b. suspensions show Tyndall effect c. colloidal show Tyndall effect d. both b and c shows Tyndall effect​

Answer 1

Answer:

Answer is (c) Colloids show Tyndall effect.

Explanation:

True solutions' particles are too small to scatter light. Most suspensions don't show Tyndall effect, but some do. Still, we can conclude that option is incorrect because most of them don't show it. With colloids, however, all of them show Tyndall effect since they're not too small or too big to scatter light. Thus, the correct option is (c).

I hope this helps!!

Answer 2

The statement that is incorrect about the Tyndall effect is a) True solution shows Tyndall effect.

Explanation:

• The Tyndall effect, also called the Tyndall phenomenon, is the phenomenon in which particles of matter in its path scatter light.
• It enables a beam of light to become visible by illuminating dust particles, etc.
• The effect is named after British physicist John Tyndall, who first studied it extensively.
• The Tyndall Effect is the effect of light scattering in colloidal dispersion while showing no light in a true solution.
• This effect is used to determine whether a mixture is a true solution or a colloid.
• A true solution does not show Tyndall Effect because the size of the constituent particles is smaller than 1nm.
