How does the pH of an acidic solution compare to that of a neutral solution?

A. The pH of an acidic solution is lower than that of a neutral solution

B. The pH of an acidic solution is higher than that of a neutral solution

C. The pH of an acidic solution is the same as that of a neutral solution

D. The pH of an acidic solution is unpredictable

Answer Explanation:

The pH scale ranges from 0 to 14, where pH values less than 7 indicate acidic solutions. Therefore, the pH of an acidic solution is lower than that of a neutral solution, which has a pH of 7.

Therefore, the Correct Answer is A.

Q #1: How does the pH of an acidic solution compare to that of a neutral solution?

A. The pH of an acidic solution is lower than that of a neutral solution

B. The pH of an acidic solution is higher than that of a neutral solution

C. The pH of an acidic solution is the same as that of a neutral solution

D. The pH of an acidic solution is unpredictable

Answer Explanation

The pH scale ranges from 0 to 14, where pH values less than 7 indicate acidic solutions. Therefore, the pH of an acidic solution is lower than that of a neutral solution, which has a pH of 7.
Q #2: Which of the following statements about strong acids is true?

A. They have a low dissociation constant (Ka)

B. They completely dissociate in solution

C. They are poor conductors of electricity

D. They have a pH greater than 7

Answer Explanation

Strong acids completely dissociate into ions when dissolved in water, resulting in a high concentration of \(H^+\) ions in solution. This complete ionization distinguishes them from weak acids.
Q #3: Which of the following properties is a characteristic of acids?

A. Bitter taste

B. Turn litmus paper blue

C. React with metals to release hydrogen gas

D. Do not Conduct electricity in solution

Answer Explanation

Acids react with certain metals to release hydrogen gas. This is a characteristic property of acids known as their reactivity with metals.
