question 10 of 32
solution a has a ph of 7, and solution b has a ph of 14. which statement best describes these solutions?

a. solution a is more basic than solution b.

b. solution b is neutral, and solution a is acidic.

c. solution b is basic, and solution a is neutral.

d. solution a is acidic, and solution b is basic.

Explanation:

To determine the nature of the solutions, we use the pH scale: a pH of 7 is neutral, a pH less than 7 is acidic, and a pH greater than 7 is basic. Solution A has a pH of 7 (neutral), and Solution B has a pH of 14 (basic, as 14 > 7). Now we analyze each option:

• Option A: Solution A (pH 7) is not more basic than Solution B (pH 14) – incorrect.
• Option B: Solution B (pH 14) is not neutral, and Solution A (pH 7) is not acidic – incorrect.
• Option C: Solution B (pH 14) is basic, and Solution A (pH 7) is neutral – correct.
• Option D: Solution A (pH 7) is not acidic – incorrect.

Answer:

C. Solution B is basic, and solution A is neutral.
