WebJan 2, 2024 · Its double negative charge makes it a very weak acid, although its conjugate base, phosphate, can be represented by four resonance structures. The Henderson-Hasselbalch equation can be applied to tell us the proportions of dihydrogen phosphate and monohydrogen phosphate present in a buffered system between pH 4 and 10.
Webis due essentially to the fact that the carboxyl group formed by hydrolysis is stabi-lized by resonance, while the carboxyl resonance in the carboxyl phosphate is in-compatible with those resonating forms of phosphate which place a positive charge on the phosphorous atom."

Radio astronomers have detected the isoformyl ion, HOC+ in outer space ... ethan monsterWebThe phosphoanhydride bonds of ATP, or the bonds between phosphate molecules, are high energy. This is due to the close proximity of positively charged phosphate and negatively charged oxygen; these charges repel. Also, there is resonance stabilization of the products of ATP hydrolysis (ADP and Pi); thus ADP is more stable than ATP. ethan mollick professorWebFree phosphate groups (Pl) have more resonance stabilization than bound ones.
