Final answer:
The approximate pH of grapefruit juice is around pH 3, which classifies it as acidic. Citric acid and other components in grapefruit juice contribute to its low pH value. Therefore, the approximate pH of grapefruit juice is C. pH 3.
Step-by-step explanation:
The approximate pH of grapefruit juice is C. pH 3. Grapefruit juice typically has a pH range from 2.9 to 3.3, indicating that it is acidic.
Substances with a pH less than 7 are considered acidic, and the lower the pH, the more acidic the substance. Given that water is neutral at pH 7 and stomach acid is very acidic at pH 1 to 2, grapefruit juice's acidic nature is shown by its pH being closer to the acidic end of the scale.
It's worth noting that acids like citric acid contribute to the low pH of grapefruit juice, and excessive exposure can result in erosion of tooth enamel.
Grapefruit juice has a pH of somewhere between 2.9 and 3.3, depending on the specific product. This makes grapefruit juice acidic. On the pH scale, anything below 7.0 is considered acidic. Therefore, the approximate pH of grapefruit juice is C. pH 3.
