A solution has a pH of 2. Which best describes the solution? a strong acid a strong base a neutral solution a weak base

Answer 1

The best solution is Strong acid

Answer 2

`\boxed {\boxed {\sf A \ strong \ acid }}`

Step-by-step 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.
