Question

Which of the following pairs of colloidal solutions have dispersed phase as liquid and dispersed medium as gas?
A. Fog, mist
B. Butter, Milk
C. Fog, smoke
D. Smoke, foam

Answer 1

Hint: There are various types of forms in which the things in the environment exist. They either exist in the natural form as pure substances or a mixture. The mixture is formed when two or more pure substances intermix to firm a third substance with different or same properties than that of the original substances mixed in the first place.

Complete answer:
> Solutions are homogeneous mixtures which contain two or more components which mix. The solution generally contains a solute and a solvent. Generally, the solvent is the component which is present in the higher quantity and the solute is smaller.
> The solute and solvent both can belong to the same or different states, like a gas can form a solution with other gas whereas gas can also form a mixture with another liquid.
> Generally, the solvent is called the dispersion medium and the solute is called the dispersed phase.
The solution, based on solute and solvent is categorized as a true solution, colloidal solution, and suspension.
> The colloid solution is the one in which the solute particles are big enough to be seen with naked eyes floating in the solvent is not completely dissolved in the solvent.
> The pair with the liquid dispersed phase and gaseous dispersed medium as gas are Fog, Mist.

So, the correct answer is Option A .

Note: Solutions can also exist in various states like solid, liquid, or gas.The solid solutions are called alloys which are the mixture of two or more elements, the liquid state of the mixtures are usually called solutions.Gases too intermix to form mixtures, since the gases are the state with the most mobile atoms so their mixtures are most usual.
