Answer and Explanation:
An acid has a pH that is less than 7. A base has a pH that is greater than 7. Something that has a pH of 7 is neutral, but since it doesn't seem that the question is asking about neutral, you can ignore that for this problem.
Situation 1: Base
Situation 2: Acid
Situation 3: Acid
Situation 4: Base
Situation 5: Acid
Situation 6: Base
A. Water directly out of the tap has a pH of 7.2. When you add carbon dioxide (blow into the water), you get a pH of 5.1. This means that the addition of carbon dioxide makes water more acidic.
B. The most basic solution will have the highest pH. This means that it will be water with bleach added to it.
C. The most acidic solution will have the lowest pH. This means that it will be water with instant coffee.
