WebThe base protonation constant Kb of morpholine (C4H8ONH) is ×2.1410−6. Calculate the pH of a 1.1M solution of morpholine at 25°C. Round your answer to 1 decimal place. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebMorpholine was more easily nitrosated by peroxynitrite at alkaline pH than at neutral pH, whereas its nitration by peroxynitrite was optimal at pH 8.5. The yield of nitrosomorpholine in this reaction was 3 times higher than that of nitromorpholine at alkaline pH, whereas 2 times more nitromorpholine than nitrosomorpholine was formed at pH <7.5.
