Is HPO4 2 a strong or weak acid?
HPO2−4 H P O 4 2 − is considered as a weak acid because removal of a proton when it donates this results in an increase in the positive charge to…
Can HPO4 2 act as an acid and a base?
a) The hydrogen phosphate ion, HPO2−4 H P O 4 2 − (aq), is amphiprotic and can act as an acid or base. Write out the chemical equation for the equilibrium hydrolysis reaction of the hydrogen phosphate ion for both acid hydrolysis and base hydrolysis.
Is H3PO4 a strong or weak acid?
Strong acids are 100\% ionized in solution. Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid, and so is ionized to a greater extent….Strong and Weak Acids and Acid Ionization Constant.
| Acid | |
|---|---|
| Weak Acids | |
| H3PO4 (phosphoric acid) | H2PO−4 (dihydrogen phosphate ion) |
| CH3COOH (acetic acid) | CH3COO− (acetate ion) |
Why HPO4 2 is weak acid?
Salts containing the anion H2PO4‾ are weakly acidic. The tendency of this ion to dissociate is greater than its tendency to hydrolyse, that is, its Ka2, is larger than its Kb. Salts containing the anion HPO4‾ are weakly basic. The tendency of this ion to hydrolyse is greater than its tendency to dissociate.
Is HPO4 2 a conjugate acid?
When we add a proton, we must conserve both mass and charge, we add H+ to HPO2−4 so the conjugate acid is simply H2PO−4 .
Is HPO4 a strong base?
Salts containing the anion HPO4‾ are weakly basic. The tendency of this ion to hydrolyse is greater than its tendency to dissociate.
What is the conjugate acid of HPO4 2 −?
Is perchloric acid a strong acid?
Perchloric acid is a corrosive inorganic liquid that is colorless, odorless, and oily in nature. A cold 70\% aqueous perchloric acid solution is considered to be a strong acid or superacid (stronger than sulfuric and nitric acids) but is not necessarily a strong oxidizing agent.
