When a beam of light is passed through colloidal solution?
Answers
Explanation:
(i) When a beam of light is passed through a colloidal solution, then light scatter from the particles. This is known as the Tyndall effect. This scattering of light illuminates the path of the beam in the colloidal solution. (ii) Upon dissolved in ferric oxide solution, NaCl dissociates into Na+ and Cl- ions.
the scattering of light by colloidal particles is known as tyndall effect. in a true solution, the solute particles are so small that they cannot scatter light falling on them. in a colloidal solution ,the particles are big enough to start a light tyndall effect can also be observed in the solutions.
1 : when a fine beam of light enters a room through a small hole due to scattering of beam of light by particles of dust and smoke in air
2 : when sunlight passes through the canopy of a dense forest as the mist containing tiny droplets of water scatter it
=> the components of a Colloidal Solutions are the dispersed phase and dispersion medium
=> dissolute like components are the dispersed particle in a colloidal form is the dispersed phase and the components in which the dispersed phase is suspended is known as a dispersion medium.
