Question

which sentence correctly describes a solution with a ph lower than the ph of distilled water?

a. the solution is neutral.

b. the solution is basic.

c. the solution is a ph indicator.

d. the solution is acidic.

Explanation:

1. Recall the pH scale: Distilled water is neutral with a pH of 7.
2. Solutions with pH < 7 are acidic, pH = 7 are neutral, and pH > 7 are basic. A pH indicator is a substance (not a solution description here). So a solution with pH lower than 7 (distilled water's pH) is acidic.

Answer:

D. The solution is acidic.
