A conjugate base formed after releasing H + ions so, for given acids H 2 O and H F conjugate base would beH 2 O → Conjugate baseOH − +H +H F → Conjugate baseF − +H +Option - A. The conjugate base is S2-. 5.3 Identify the conjugate acids of the following bases? (a) C 5H 5 ... that HI is a stronger acid than HF which is a stronger acid than H 2S, a partial order of proton affinity is I-<F-< HS-. Since NH 3 is a very weak acid, NH 2-must be a very strong base. Therefore, our final list, in order of increasing proton affinity, is I-<F-< HS-<NH 2-. 5.5 Which bases are too ... Which is an acid-conjugate base pair? HF and H3O+ HF and F H2O and HF H2O and F. Answers (1) Sri 21 September, 13:10. 0. Water is an amphoteric compound. This means it could be a base or an acid, depending on the substance it is to be reacted with. In this case, water is a base because HF is an acid. Now, if the reactant is an acid, its form after the reaction is called the conjugate pair ... Since HF has donated a proton HF is an acid , H20 has accepted a proton so water is a base .F- can accept a proton so F- is a base but we will call it conjugate base of HF beacuse it is generated by removing a proton from the acid HF so it is the conjugate base to the acid HF and similary , the H2O has accepted the proton so it is a base and H3O+ is the conjugate acid to the base H2O since it is generated when the H2O accpeted the proton and H3O+ can now donate the proton so it is an acid. •HF is a base and H3O+ is its conjugate acid. •HF is an acid and H2O is its conjugate base. , HF, HPO. 4 2–, HCO + Practice Exercise. Solution Analyze: We are asked to give the conjugate base for each of a series of species and to give the conjugate acid for each of another series of species. Plan: The conjugate base of a substance is simply the parent substance minus one proton, and the conjugate Conjugate base for Br onsted acids H2O and HF are : (1) OH– and H2F+, respectively. (2) H3O+ and F–, respectively. (3) OH– and F–, respectively. (4) H3O+ and H2F+, respectively. neet 2019. Please log in or register to add a comment.
