The species with the greatest proton affinity will be the strongest base, and its conjugate acid will be the weakest acid. C5H5NHBr is acidic because it dissociates into Br- and C5H5NH+ ions. Answer to: Pyridine, C5H5N, has Kb = 1.7 x 10-9 and reacts with water as C5H5N + H2O arrow C5H5NH+ + OH-. Pyridine is protonated by reaction with acids and forms a positively charged aromatic polyatomic ion called pyridinium. Problem: What is Kb for pyridine (C5H5N) if Ka for its conjugate acid is 5.9 x 10-6 at 25°C?A) 1.7 x 10-9 B) 5.9 x 108C) 1 x 1014D) 1.7 x 1019 FREE Expert Solution We are asked to find K b for C 5 H 5 N given that the Ka of its conjugate acid (C 5 H 5 NH + ) is 5.9x10 -6 (a) C5H5N(aq) + H2O(l… Base ///// Kb. In The Reaction: C5H5N + H2O C5H5NH+ + OH- The Bronsted-Lowry Conjugate Acid Is: Select One: A. C5H5NH+ B. OH- C. H2O D. C5H5N This question hasn't been answered yet Ask an expert You should make use of Table 5.1 to answer this question. The weakest acid will have the smallest value of K Its conjugate base is Pyridine C5H5N. First of all, C5H5N is a base, not an acid and is also known as Pyridine, an organic compound similar to benzene in structure. NH4⁺ What is the conjugate acid of HSO4⁻? 7 hpo4-2 12. 5.4 List the bases HS-, F-, I-, and NH 2-in order of increasing proton affinity? Sulfuric acid. Identify the conjugate acid of C5H5N and calculate its KA. The conjugate acid is HCN. Solution for In each reaction, identify the Brønsted–Lowry acid, the Brønsted–Lowry base, the conjugate acid, and the conjugate base. C5H5N+H2CO3⇌C5H6N⁺+HCO3⁻ In the reaction shown, the conjugate of C5 H5N is... C5H6N⁺ Which of the following is a diuretic acid? Which of the following cannot act as a Bronsted base? Br- comes from a strong acid, making its conjugate neutral. H2SO4. Calculate the Ka for lactic acid if a 0.
