Which of the following best describes bases in solution?

• A. They produce hydrogen ions
• B. They neutralize acids
• C. They release hydroxide ions
• D. Both B and C

Answer: (D)

The correct description of bases in solution includes their ability to both neutralize acids and release hydroxide ions. Bases are substances that can accept protons or donate electron pairs, and when they dissolve in water, they increase the concentration of hydroxide ions (OH⁻). This release of hydroxide ions is a fundamental characteristic of bases, contributing to their alkaline nature. Additionally, because bases can react with acids to form salt and water, they effectively neutralize acidic solutions. This neutralization is a crucial aspect of acid-base chemistry, highlighting the balancing act between these two types of substances. Therefore, the choice that combines both the neutralization of acids and the release of hydroxide ions accurately captures the defining behavior of bases in solution.
