WebRegarding to your question, the strongest acidic pKa refers to N-H dissociation of the indol part, while the strongest basic pKa refers to the dissociation of the protonated tertiary … Web7. Methanesulfonic acid is the stronger acid. The lower the pKa, the stronger the acid. A lower pKa is associated with a larger Ka which signifies greater dissociation. The large relative difference in acidity in this case can be most easily seen by gauging the relative basicities of the conjugate bases. The weaker the base, the stronger the ...

WebpKa = – log Ka. For example, the p Ka of hydrochloric, nitrous, and acetic acids are: pKa (HCl) = – log 1.3 x 10 6 = -6. pKa (HNO2) = – log 7.2 x 10 -4 = 3.1. pKa (CH3CO2H) = – log 1.7 x 10 -5 = 4.76. Based on the Ka values, HCl is the strongest acid followed by HNO 2, and then CH 3 CO 2 H. HCl has the smallest pKa, while the weakest ...

WebStronger Base = Smaller K a and Larger pK a of the Ammonium ion Like ammonia, most amines are Brønsted-Lowry and Lewis bases, but their base strength can be changed enormously by substituents. Most simple alkyl amines have pK a 's in the range 9.5 to 11.0, and their aqueous solutions are basic (have a pH of 11 to 12, depending on concentration). WebFeb 4, 2024 · A large Kb value indicates the high level of dissociation of a strong base.
