An example of a weak base is pyridine (C₅H₅N). Explain what happens when C₅H₅N is dissolved in water.

• A. When dissolved in water, a small amount of C₅H₅N acts as a base that accepts H⁺ ions from water yielding a solution of the unreacted C₅H₅N and small amounts of C₅H₅NH⁺ and OH⁻.
• B. When dissolved in water, a small amount of C₅H₅N acts as a base that accepts H⁺ ions from water yielding a solution of C₅H₅NH⁺ and OH⁻.
• C. When dissolved in water, C₅H₅N acts as a base that accepts H⁺ ions from water yielding a solution of C₅H₅NH⁺ and OH⁻.
• D. When dissolved in water, C₅H₅N acts as a base that accepts H⁺ ions from water yielding a solution of C₅H₅N and OH⁻.
