The conjugate base of a weak acid is a weak base, why? Edit: At the equivalence point, the solution contains the dissolved salt $\ce{CH3NH3Cl}$, dissociated to $\ce{CH3NH3+ + Cl-}$, as @MaxW noted. Methylamine is a reasonably strong base as bases go (#pK_B = 3.36#); it is also a potent nucleophile. Conjugate acids of strong bases and conjugate bases of strong acids CH3NH3Cl (acidic) CH3NH2 + H2O CH3NH3 + + OH-(conjugate acid) HCl H+ + Cl- (virtually all dissociated) Is the species in solution acidic, basic, or neutral? Publisher: Cengage Learning. Find the acid and base in the following reaction: Identify the following if acidic or basic. 10th Edition. Cl- is a very weak conjugate base so its basicity is negligible. Answer : CH3NH3NO3 is acid What is an acid, base, neutral ? Routing number of commercial bank of Ethiopia? + HA + H 2 O H 3 O + A Acid Base Conjugate Conjugate Acid of H 2 O Base of HA HA is the proton donor (the acid) and H 2 O is the proton acceptor (the base). So, you're dealing with a sample of #CH_3NH_3Cl# that you've diluted to a total volume of #"500.00 mL"#.The aliquot, which measures #"15.00 mL"#, is titrated with #"47.32 mL"# of #NaOH#.. A base is defined as a proton acceptor or lone pair donor. Often, these problems are given with the K b of the base and you have to calculate the value of the K a.You do so with this equation: K a K b = K w. You will see such a situation starting in the fifth example as well as scattered through the Therefore the salt is acidic because of CH3NH3+, a Bronsted acid.
