Answer 2

Answer:

The correct answer is option (A) sodium chloride, which acts as a pure substance.

Explanation:

• Pure substance:- The matter which has an inconvertible chemical conformation and isolated properties (composed of similar elements or compounds) is known as a pure substance.

• Sodium chloride:- sodium chloride is generally known as common or ordinary table salt, it is a uniform and identical composition type substance and all its samples are identical chemically.

• Cold drink:- commonly contains $H_{2} O$ (water), sweetening agents, carbon dioxide, artificial flavoring agents, coloring agents, chemical preservatives, antioxidants, and foaming agents that have different types of convertible chemical conformation with non-isolated properties which lead to it being a too impure substance.

• Aerosol:- aerosols are commonly the suspension of liquid droplets in air or other gases. It could be natural or anthropogenic. Natural aerosols are fog or mist, dust, forest exudates, and geyser steam that is a mixture, not a pure substance.

• Clay:- it consists of iron substitutes for aluminum and magnesium in varying degrees and appreciable quantities of potassium, sodium, and calcium are frequently present as well, which is why it is not considered a pure substance.

             Hence, (A)sodium chloride acts as a pure substance.
