Conjugate base hpo4 2
Jul 17, 2023 · An acid and a base which differ only by the presence or absence of a proton are called a conjugate acid-base pair. Thus NH 3 is called the conjugate base of NH 4+, and NH 4+ is the conjugate acid of NH 3. Similarly, HF is the conjugate acid of F –, and F – the conjugate base of HF. Example 11.13.1 11.13. 1 : Conjugate Pairs. H 3 P O 4 (a q) + H 2 O (l) H 2 P O 4 − (a q) + H 3 O + (a q) A conjugate acid- base pair is such that the species constituting the pair differ in one proton ( H + ) . In the above reaction, acid H 3 P O 4 loses a proton to give its conjugate base H 2 P O 4 − .The resulting base is called the conjugate base. The same is true for bases-- when in equilibrium, it will accept a proton, and become a conjugate acid. Here are the equilibrium expressions: HPO 4 2-+ H 2 O …
