Question

Which of the following gases is most soluble in water?

• A. Oxygen
• B. Nitrogen
• C. Carbon dioxide
• D. Hydrogen

Hint:

Gases like CO\(_2\) that can react with water are usually more soluble than nonreactive gases like N\(_2\) and O\(_2\).

Answer 1

The Correct Option is C

The dissolution of gases in water is influenced by their chemical properties and their interaction with water molecules. Considering the provided gases: - Oxygen (O\(_2\)) exhibits restricted solubility in water. - Nitrogen (N\(_2\)) demonstrates lower solubility in water due to its nonpolar characteristics. - Carbon dioxide (CO\(_2\)) exhibits substantial solubility in water owing to its capacity to generate carbonic acid (H\(_2\)CO\(_3\)) upon dissolution. - Hydrogen (H\(_2\)) possesses limited solubility in water. Answer: Carbon dioxide displays the highest solubility in water; therefore, option (3) is the correct selection.
