Final answer:
A solution with a pH of 2 is described as acidic because it has a lower pH than the neutral pH of 7, indicating a high concentration of hydrogen ions.
Step-by-step explanation:
A solution that has a pH of 2 could best be described as being acidic. The pH scale is a measure of how acidic or basic a solution is.
A neutral solution has a pH of 7, acidic solutions have a pH less than 7, and basic solutions have a pH greater than 7. Since a pH of 2 is much lower than 7, it indicates a high concentration of hydrogen ions (H3O+), which classifies the solution as acidic.
Here are some additional examples for reference:
- Human blood, pH = 7.4, is slightly basic.
- Household ammonia, pH = 11.0, is basic.
- Cherries, pH = 3.6, are acidic.
