For example, a typical carboxylic acid has a pK a of around 4. A rule in organic chemistry is "the weaker the base, the stronger the conjugate acid". Amines react with acids to accept a hydrogen ion, making them an acid according to the Bronsted-Lowry definition. As an amine it is considered a weak base. Is CH3NH2 an acid or base? Strong or Weak - Topblogtenz Can you tell me the conjugate base of #NH_3#? But 1º, 2º, or NH3 all react well. Ammonia is actually itself a weak base, so its conjugate base NH2- is an incredibly strong base so it can get an extra proton to regenerate NH3 . 3.2 * 10 9. Their basic properties include the reactions with dilute acids, water and copper (II) ions. Solved CUSTFR OSOFT O acids NH2. NH3 bases H20, OH Question | Chegg.com ∙ 2010-07-14 22:48:32.

TABLE OF CONJUGATE ACID-BASE PAIRS Acid Base K a (25 oC) HClO 4 ClO 4 - H 2 SO 4 HSO 4 - HCl Cl- HNO 3 NO 3 - H 3 O + H 2 O H 2 CrO 4 HCrO 4 - 1.8 x 10-1 H 2 C 2 O 4 (oxalic acid) HC 2 O 4 - 5.90 x 10-2 [H 2 SO 3] = SO 2 (aq) + H2 O HSO NH2 − (base)+H + →NH3 (conjugate acid) NH 3 is a base: it can accept a proton(H +) and form conjugate acid. What is the Brønsted-Lowry base in this reaction: NH2−+CH3OH→NH3+CH3O− ... . (Acting as a Lewis Base) NH3 + H+ → NH4+ (Acting as a Lewis Acid) NH3 → NH2- + H+ The reason behind NH3 acting as a Lewis Base We would have the conjugate base to a carboxylic acid, which is a carboxylate anion.
