What happens to the pH of pure water when a few drops of lemon juice are added?
-
A.
The pH remains the same
-
B.
The pH decreases
-
C.
The pH increases
-
D.
The pH becomes neutral
Correct Answer:
B. The pH decreases
Explanation:
When lemon juice is added to pure water, the pH level drops because lemon juice is highly acidic due to its citric acid content. Pure water has a neutral pH of 7, but the introduction of hydrogen ions from the acid increases the acidity of the solution, resulting in a lower pH value. This chemical reaction consistently makes the liquid more acidic rather than neutral or basic.
