What happens to the conductivity of a weak acid solution as it becomes more diluted?

A. Conductivity increases

B. Conductivity decreases

C. Conductivity remains constant

D. It depends on the acid

Answer Explanation:

As a weak acid solution becomes more diluted, the concentration of ions decreases, leading to a decrease in conductivity. Weak acids only partially ionize in solution, resulting in fewer ions available to conduct electricity.

Therefore, the Correct Answer is B.

Q #1: What happens to the conductivity of a weak acid solution as it becomes more diluted?

A. Conductivity increases

B. Conductivity decreases

C. Conductivity remains constant

D. It depends on the acid

Answer Explanation

As a weak acid solution becomes more diluted, the concentration of ions decreases, leading to a decrease in conductivity. Weak acids only partially ionize in solution, resulting in fewer ions available to conduct electricity.
Q #2: 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 #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.
