Match column I (process) with column II (application)
$\begin{array}{|l|l|l|l|} \hline & \text{Column I} & & \text{Column II} \\ \hline \text{A)} & \text{Dialysis} & \text{a)} & \text{Cleansing action of soap} \\ \hline \text{B)} & \text{Peptization} & \text{b)} & \text{Coagulation} \\ \hline \text{C)} & \text{Emulsification} & \text{c)} & \text{Colloidal Solution Preparation} \\ \hline \text{D)} & \text{Electrophoresis} & \text{d)} & \text{Purification of colloidal solution} \\ \hline \end{array}$
- A$\mathrm{A}=\mathrm{d}, \mathrm{B}=\mathrm{a}, \mathrm{C}=\mathrm{c}, \mathrm{D}=\mathrm{b}$
- Correct answerB$\mathrm{A}=\mathrm{d}, \mathrm{B}=\mathrm{c}, \mathrm{C}=\mathrm{a}, \mathrm{D}=\mathrm{b}$
- C$A=c, B=b, C=d, D=a$
- D$A=b, B=c, C=a, D=d$
Solution
Matching the processes with their applications:
Dialysis purifies colloidal solutions using a semi-permeable membrane, matching with (d).
Peptization forms colloids from precipitates with an electrolyte, matching with (c).
Emulsification disperses immiscible liquids, fundamental to the cleansing action of soap, matching with (a).
Electrophoresis moves charged colloids to electrodes causing coagulation, matching with (b).
Thus, $A \to d$, $B \to c$, $C \to a$, $D \to b$, corresponding to option B.
Final answer: $\boxed{\text{B}}$
Hence, the correct answer is option: 'B'.
