Final answer:
The solution has a ph over 7 is D. water.
Step-by-step explanation:
A solution with a pH over 7 is considered basic. Bases are substances that have a lower concentration of hydronium ions than pure water, causing them to have a higher pH. Orange juice, vinegar, and baking soda are all examples of substances that have a pH lower than 7, making them acidic.
However, water has a pH of 7, which means it is neutral. Therefore water has a pH of 7, making it neutral. The correct answer is D. water.
