Read each question carefully and answer to the best of your ability. Refer to the provided pH scale diagram as needed.
The pH scale is a measure of how acidic or basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas pHs of greater than 7 indicate a base.
1. Which of the following pH values indicates a strong acid?
pH 12
pH 7
pH 2
pH 9
2. A solution with a pH of 7 is considered:
Acidic
Basic
Neutral
Strongly acidic
1. A substance with a pH of 10 is considered an acid.
True
False
2. The pH scale measures the concentration of hydrogen ions in a solution.
True
False
1. Lemon juice has a pH of approximately 2, making it an solution.
2. A substance that has a pH greater than 7 is called a .
3. Pure water has a pH of , which is considered neutral.
1. Explain the difference between an acid and a base in terms of hydrogen ion concentration.
2. Give two examples of common household items that are acidic and two that are basic.
