Hpo42 Acid Or Base. Even things considered strong acids can be forced to act like a base by being mixed with an acid even stronger than they are. Again, conserve mass and charge, and h p o2− 4 results.
P k a ( n a x 2 h p o x 4) = 12.35, so the equilibrium ( 3) will be predominant. And what is the conjugate base of this beasty? Thus acting as an acid. Web being an acid or a base is situational. So here it acts as a base. The ion you list will be a base if mixed with an acid and an acid if mixed with a base. Phosphoric acid (h 3 po 4) is an acid. Web as we know a h2po4 is a bronsted acid and hence it will donate its proton. Phosphoric acid, h 3p o4, is the parent acid. E) h2o is a base and h2po4 is its conjugate acid.
If it loses a proton, h +, we conserve both mass and charge, and h 2p o− 4 results. But in the case when h2po4 will accept a hydrogen ion, it will lead to the formation of h3po4. Phosphoric acid, h 3p o4, is the parent acid. E) h2o is a base and h2po4 is its conjugate acid. So here it acts as a base. We know that with polyprotic acids, after the first proton is lost, subsequent amphiprotic acids formed are substantially harder to deprotonate (removing an h+ from an increasingly negative anion molecule is harder); Even things considered strong acids can be forced to act like a base by being mixed with an acid even stronger than they are. D) h20 is a base and oh is its conjugate acid. I agree that this is all too easy to. Thus, it acts both as acid and base. Thus acting as an acid.
