Question

5. Explain the electrical dialysis method of purification of colloidal solution.
​

Answer 1

Explanation:

Purification of Colloidal Solution

(i) The process of separating the particles of colloid from those of crystalloid, by means of diffusion through a suitable membrane is called dialysis. ... (ii) To increase the process of purification, the dialysis is carried out by applying electric field

Answer 2

$\huge\boxed{\fcolorbox{cyan}{blue}{Question }}$

xplain the electrical dialysis method of purification of colloidal solution.

$\huge\boxed{\red{Answer }}$

 this process dialysis of colloidal solution is carried under the effect of electric field. Some potential is applied between the metal screens that support the membranes. Due to this potential, the speed of the ions moving in the direction of opposite electrodes is increased. Thus, the rate of dialysis is increased.
