Which of the following statements about the taste of bases is true?

A. Bases have a sweet taste

B. Bases have a bitter taste

C. Bases have a sour taste

D. Bases have no taste

Answer Explanation:

Bases have a bitter taste. However, tasting chemicals is not safe and should never be done.

Therefore, the Correct Answer is B.

Q #1: Which of the following properties is a characteristic of bases?

A. React with metals to release hydrogen gas

B. Turn litmus paper red

C. Have a sour taste

D. Conduct electricity in solution

Answer Explanation

Bases do not react with metals to release hydrogen gas. This property distinguishes them from acids, which do react with metals to produce hydrogen gas.
Q #2: Which of the following statements about the pH of bases is correct?

A. Bases have a pH greater than 7

B. Bases have a pH equal to 7

C. Bases have a pH less than 7

D. Bases have a pH of 7 and can vary based on concentration

Answer Explanation

Bases have a pH greater than 7 on the pH scale, indicating their alkaline nature. The pH of a base solution increases as the concentration of hydroxide ions (\(OH^-\)) increases.
Q #3: What is the effect of bases on the pH of a solution?

A. Bases increase the pH

B. Bases decrease the pH

C. Bases have no effect on the pH

D. It depends on the concentration of the base

Answer Explanation

Bases increase the pH of a solution. As bases ionize in water, they release hydroxide ions (\(OH^-\)), which react with \(H^+\) ions from water, thereby decreasing the concentration of \(H^+\) ions and increasing the pH.
