Which of the following will not show Tyndall effect?
Which of the following will not show Tyndall effect?
The correct option is C Sugar solution
The explanation for the correct option:
- Colloids are mixtures having 1-1000 nm sized particles dispersed in the medium
- Dispersed phase: Particles dispersed in the medium
- Dispersion medium: The medium in which the particles are dispersed
- Depending on the states off the dispersed phase and dispersion medium, different types of colloids are present
- When the light passed through the colloidal solution, path of light becomes visible due to the scattering of light by the 1-1000 nm-sized dispersed particles is called Tyndall effect
(C) Sugar solution: It belongs to the category of true solution where the size of the dissolved particle is less than 1 nm where it doesn't show the Tyndall effect.
The explanation for the incorrect option:
(A) Soap solution: It is a type of colloid where the dispersed phase is gas and the dispersion medium is liquid called Foam. It can show Tyndall effect.
(B) Starch solution: It is a type of colloid where the 1-1000 nm-sized particles are dispersed in a medium. It can show Tyndall effect.
(D) Gold sol: It is a type of colloid where the dispersed phase is solid and dispersion medium is liquid and it can show Tyndall effect.
Therefore, option (C) is correct.i.e., sugar solution does not show Tyndall effect.
