7 hpo4-2 12. Which of the following cannot act as a Bronsted base? 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 5.4 List the bases HS-, F-, I-, and NH 2-in order of increasing proton affinity? 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. Its conjugate base is Pyridine C5H5N. 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 You should make use of Table 5.1 to answer this question. The species with the greatest proton affinity will be the strongest base, and its conjugate acid will be the weakest acid. Base ///// Kb. Sulfuric acid. The conjugate acid is HCN. Br- comes from a strong acid, making its conjugate neutral. C5H5N+H2CO3⇌C5H6N⁺+HCO3⁻ In the reaction shown, the conjugate of C5 H5N is... C5H6N⁺ Which of the following is a diuretic acid? C5H5NHBr is acidic because it dissociates into Br- and C5H5NH+ ions. (a) C5H5N(aq) + H2O(l… Solution for In each reaction, identify the Brønsted–Lowry acid, the Brønsted–Lowry base, the conjugate acid, and the conjugate base. First of all, C5H5N is a base, not an acid and is also known as Pyridine, an organic compound similar to benzene in structure. Calculate the Ka for lactic acid if a 0. The weakest acid will have the smallest value of K NH4⁺ What is the conjugate acid of HSO4⁻? Identify the conjugate acid of C5H5N and calculate its KA. H2SO4.
