pH: Acid or Base
True or False: For each false statement, change the underlined word(s) to the correct word(s).
1. _________________ A strong acid gives off many hydroxide ions in water.
2. _________________ The pH of a solution is found to be 5.5. This means the solution is basic.
3. _________________ A pH of 10 is more basic than a pH of 8.

7. _________________ A low pH tells you that few hydrogen ions are present.
8. _________________ As a solution becomes more basic, its pH decreases.
9. _________________ Air pollution from industry often causes rainwater to become acidic.
10. _________________ Unpolluted rainwater is slightly acidic.
Completion: Write in the word(s) which best complete(s) each statement.
