Answer:
[tex]\boxed {\boxed {\sf A \ strong \ acid }}[/tex]
Explanation:
The pH scale measures how acidic or basic a solution is. It is based off of the number of H⁺ and OH⁻ ions in a solution, which is where the pH gets its name (pH= potential of hydrogen).
Here is how the pH scale works:
- Less than 7= acid (more H⁺ ions)
- Exactly 7= neutral (equal H⁺ and OH⁻ ions)
- Greater than 7 = base (more OH⁻ ions).
The strength can be determined by how far away the number is from 7.
- If it closer to 0, it is a stronger acid.
- If it closer to 14, it is a stronger base.
The solution given has a pH of 2. This is closer to 2, so it is a strong acid.
