Question:

$\text{The correct match amongst the following is -}$ $\begin{array}{|c|c|} \hline \text{Physical states of the dispersed phase and dispersion medium} & \text{Type of colloid} \\ \hline \text{a. D.P = solid; D.M = liquid} & \text{i. Foam} \\ \text{b. D.P = solid; D.M = gas} & \text{ii. Emulsion} \\ \text{c. D.P = liquid; D.M = liquid} & \text{iii. Aerosol} \\ \text{d. D.P = gas; D.M = liquid} & \text{iv. Sol} \\ \hline \end{array}$ $(\text{D.P = dispersed phase, and D.M = dispersion medium})$

Options:

1. $\begin{array}{|c|c|c|c|} \hline \text{a} & \text{b} & \text{c} & \text{d} \\ \hline \text{iv} & \text{iii} & \text{ii} & \text{i} \\ \hline \end{array}$
2. $\begin{array}{|c|c|c|c|} \hline \text{a} & \text{b} & \text{c} & \text{d} \\ \hline \text{iii} & \text{iv} & \text{i} & \text{ii} \\ \hline \end{array}$
3. $\begin{array}{|c|c|c|c|} \hline \text{a} & \text{b} & \text{c} & \text{d} \\ \hline \text{iv} & \text{i} & \text{iii} & \text{ii} \\ \hline \end{array}$
4. $\begin{array}{|c|c|c|c|} \hline \text{a} & \text{b} & \text{c} & \text{d} \\ \hline \text{i} & \text{iii} & \text{ii} & \text{iv} \\ \hline \end{array}$

Solution:

$\text{HINT: Dispersed phase represents solute and dispersion medium represents the solvent}$ $\text{Explanation:}$ $\text{One criterion for classifying colloids is the physical state of the dispersed phase and dispersion medium. Depending upon the type of the dispersed phase and the dispersion medium, the correct answer is as follows:}$ $\begin{array}{|c|c|} \hline \text{Physical states of the dispersed phase and dispersion medium} & \text{Type of colloid} \\ \hline \text{a. D.P = solid; D.M = liquid} & \text{i. Sol} \\ \text{b. D.P = solid; D.M = gas} & \text{ii. Aerosol} \\ \text{c. D.P = liquid; D.M = liquid} & \text{iii. Emulsion} \\ \text{d. D.P = gas; D.M = liquid} & \text{iv. Foam} \\ \hline \end{array}$
