Answer :
Sure, let's analyze the ions listed in each option and their likelihood of being found in a glass of water.
Water, chemically denoted as [tex]\( H_2O \)[/tex], is composed of hydrogen and oxygen atoms. When water dissociates, it breaks into hydrogen ions ([tex]\( H^+ \)[/tex]) and hydroxide ions ([tex]\( OH^- \)[/tex]).
Let's go through the options:
Option A: [tex]\( H^+ \)[/tex]
- This represents a hydrogen ion. In water, the hydrogen ion is a common product of the dissociation of water molecules. It's known that water self-ionizes to form [tex]\( H^+ \)[/tex] and [tex]\( OH^- \)[/tex].
Option B: [tex]\( N^+ \)[/tex]
- This represents a nitrogen ion. Nitrogen ions are not typically found in a glass of water unless there's some special contamination. Nitrogen usually forms compounds like [tex]\( NH_3 \)[/tex] (ammonia) in solution, rather than simple [tex]\( N^+ \)[/tex] ions.
Option C: [tex]\( O_2 \)[/tex]
- This represents molecular oxygen. While oxygen can dissolve in water (up to a certain limit) and is essential for aquatic life, it is not an ion; it remains in its molecular form [tex]\( O_2 \)[/tex].
Option D: [tex]\( O^- \)[/tex]
- This represents a negatively charged oxygen ion. Negatively charged oxygen ions are not commonly found in a glass of water. Oxygen commonly forms oxides, peroxides, and other compounds in a different context.
Given these analyses:
The ion found in a glass of water from the listed options is indeed [tex]\( H^+ \)[/tex].
So, Option A ([tex]$H^+$[/tex]) is the correct answer.
