sodium phosphate dibasic heptahydrate pka

Hydrognophosphate de potassium — Wikipdia

Le phosphate dipotassique est souvent utilis par des sportifs en effet on peut remarquer qu' l'inverse de l'acide phosphorique le pKa 3 de l'acide tant trs faible le taux d'acidit dans l'estomac ne fluctuera pas Ainsi certains sportifs l'utilisent pour que l'ion phosphate joue un rle important dans le cycle du transport de l'nergie par l'ATP cette molcule favorisera
