Ka of ch3nh3+
WebbMethylamine is a weak base, and the Kb for methylamine is 3.7 times 10 to the negative 4. Our problem asks us to calculate the Ka value for the methylammonium ion which is CH3NH3 plus. We're talking about a conjugate acid-base pair. There's one proton difference between those. Therefore we can use our equation, Ka times Kb is equal to Kw. WebbCH3NH2 + H+ ---> CH3NH3+ 2) When 0.1 mole of CH3NH2 and 0.08 mole of HCl react, this is what remains after the reaction: 0.02 mol CH3NH2 0.08 mol CH3NH3+ 3) Since we now have a buffer, we will use the Henderson-Hasselbalch Equation: First, however, we will use the Kb to get the pKa. pKa + pKb = 14 pKb = −log 5 x 10¯4 = 3.30103

Webb7 mars 2024 · CH3NH3+ (aq) + H2O (l) ⇌ CH3NH2 (aq) + H3O+ (aq) The equilibrium constant for this reaction is: Ka = Kw / Kb = 1.0 × 10^-14 / 4.4 × 10^-4 = 2.27 × 10^-11 The initial concentration of CH3NH3+ is 0.25 M, and since it hydrolyzes to produce H3O+, the concentration of H3O+ at equilibrium is also equal to x. WebbCalculate the pH of a buffer solution that is 0.108 M in CH3NH2 and 0.308 M in CH3NH3+ Given that Ka for HF is 6.3 x 10-4 at 25^o C, what is the value of Kb for F- at 25^o C? Given that Kb for CH_3NH_2 is 5.0 10-4 at 25^o C, what is the value of Ka for CH3NH3 at 25^o C? A 2.9M methylamine (CH3NH2) solution is 1.3% ionized.
