How do acids affect the electrical conductivity of a solution?

A. They decrease conductivity

B. They increase conductivity

C. They have no effect on conductivity

D. It depends on the concentration of the acid

Answer Explanation:

Acids increase the electrical conductivity of a solution. This is because acids ionize in water to produce hydrogen ions (\(H^+\)), which carry an electric charge.

Therefore, the Correct Answer is B.

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 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.
Q #3: How do acids affect the electrical conductivity of a solution?

A. They decrease conductivity

B. They increase conductivity

C. They have no effect on conductivity

D. It depends on the concentration of the acid

Answer Explanation

Acids increase the electrical conductivity of a solution. This is because acids ionize in water to produce hydrogen ions (\(H^+\)), which carry an electric charge.
