What happens to the pH of pure water when a few drops of lemon juice are added?
-
A.
The pH becomes neutral
-
B.
The pH increases
-
C.
The pH decreases
-
D.
The pH remains the same
Correct Answer:
C. The pH decreases
Explanation:
Adding lemon juice to pure water decreases its pH because lemon juice contains citric acid, which releases hydrogen ions into the solution. Since pH is a measure of hydrogen ion concentration, an increase in these ions makes the water more acidic, resulting in a lower pH value on the scale.
