Here’s a nifty way to look at it: Suppose we have the following reaction: NH3 ←> NH4+ + OH- We know that this is a shorter way to write: NH3 + H2O ←> NH4+ + OH- Which is basically telling us that NH3 takes away a hydrogen proton from H2O to become... A more general definition is that a conjugate base is the base member, X-, of a pair of compounds that transform into each other by gaining or losing a proton. The conjugate base is able to gain or absorb a proton in a chemical reaction. The conjugate acid donates the proton or hydrogen in the reaction. Identify the two conjugate acid-and-base pairs . involved in each of the following reactions. NH3 + H3PO4 NH4+ + H2PO4- N3- + H2O OH- + HN3 . H3O+ + OH- 2H2O Start studying Conjugate acid &base. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Simply remove H^+ from your base from your base formula; conserve mass and charge. The conjugate base of H_3PO_4, phosphoric acid, is H_2PO_4^-. The conjugate base of dihydrogen phosphate is HPO_4^(2-) (so you know the conjugate acid, why?). Conjugate base is allways ONE proton H+ less than its acid which it is conjugated to.So H2PO4-(monohydrogen phosphate) is the conjugate base of the acid: H3PO4 One side is the acid. The other side the base. Each card forms a conjugate acid-base pair. Learn with flashcards, games, and more — for free. Chapter 17 2) a) HCl and CH3COOH are both acids.A buffer must have an acid/base conjugate pair. b) NaH2PO4 and Na2HPO4 are an acid/base conjugate pair. They will make an excellent buffer. c) H2CO3 and NaHCO3 are also an acid/base conjugate pair and they will make an excellent buffer. Which of the following is the conjugate base of HPO42-? a. H2O b.
