Question: When an electric current is passed through a Sol?

On passing an electric current through a sol, the colloidal particles move towards oppositely charged electrode. This phenomenon is called electrophoresis. Positively charged particles move towards the cathode while negatively charged particles move towards the anode.

What happens when electric current is passed through a sol?

(iii) When electric current is passed through a colloidal solution, the dispersed phase (or colloidal particles) move towards oppositely charged electrodes. On reaching the electrode, they lose their charge and get coagulated.

What happens when a an electric current is passed through a sol B NaCl is added to ferric hydroxide sol?

(ii) When NaCl is added to ferric oxide sol, it dissociates to give Na+ and Cl ions. Particles of ferric oxide sol are positively charged. Thus, they get coagulated in the presence of negatively charged Cl ions.

What happens when a beam of light is passed through a sol?

When a beam of light is passed through a colloidal solution, then a scattering of light is observed. This is known as the Tyndall effect. This scattering of light illuminates the path of the beam in the colloidal solution.

What is observed when electric current is passed through?

Under the influence of an electric current, the colloidal particles move towards the oppositely charged electrode. When they come in contact with the electrode, they lose their charge and coagulate.

When an electric current is passed through a solution?

When an electric current is passed through a conducting solution, chemical reaction is caused being referred to as the chemical effects of electric current.

What happens when a beam of light is passed through a colloidal solution B What is electrophoresis?

a) When beam of light passed through a colloidal solution of As2S3. the path of the light become visible beacuse of the tyndall effect. … c)The movement of colloidal particles under an applied electric potential is called electrophoresis.

When light is passed through a colloidal solution?

4 Answers. (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.

When beam of light is passed through a colloidal sol the path of the beam gets illuminated?

When a beam of light is passed through the solution there is no scattering of light but scattering of light occurs when it is passed through colloidal solution. This effect is called Tyndall’s effect. Due to scattering of light by colloidal particles the path of light gets illuminated.

When a beam of light is passed through starch sol?

a starch solution is a colloidal solution. in a colloidal solution, particles are relatively big. so, when a beam of light is passed, the path of light is visible. it scatters.

What happens when a beam of light is passed through feoh3 sol?

(i) The path of light becomes visible because colloidal particles scatter light (Tyndall effect). (ii) Fe(OH)3 gets coagulated.

What would happen to light if it passes through a solution?

When light is passed through a true solution, the dissolved particles are too small to deflect the light. However, the dispersed particles of a colloid, being larger, do deflect light. The Tyndall effect is the scattering of visible light by colloidal particles.

What happens when a beam of light is passed through a colloidal solution name this phenomenon?

On passing a beam of light through a colloidal solution, the colloidal particles absorb light energy and then emit it in all the possible directions. This phenomenon is called scattering of light or Tyndal effect.
