How does the concentration of hydrogen ions correlate with the strength of an acid?
The strength of an acid increases with a higher concentration of hydrogen ions.
Can a strong acid exist in a dilute solution, and if so, provide an example?
Can a strong acid exist in a dilute solution, and if so, provide an example?
Yes, a strong acid can exist in a dilute solution; for example, dilute nitric acid.
What is the pH value of a dilute nitric acid solution, and what does it signify about its acidity?
What is the pH value of a dilute nitric acid solution, and what does it signify about its acidity?
A dilute nitric acid solution has a pH of about 2, indicating it is strongly acidic.

Study Notes
Strength of Acids
- Acid strength is determined by the concentration of hydrogen ions (H⁺) in a solution.
- A higher concentration of H⁺ ions corresponds to a stronger acid.
- It is possible to have a dilute solution of a strong acid.
Example of Strong Acid
- Dilute nitric acid serves as an example of this phenomenon.
- Despite being a strong acid, dilute nitric acid can have a pH of about 2.
- The low pH indicates high H⁺ concentration, but the overall solution may not be very concentrated.
