phosphate
No, the equation is: HPO4-2 → H+ + PO4-3 The HPO4-2 and PO4-3 are conjugate acid base pairs.
The conjugate base of HPO4^-2 is PO4^-3 because when HPO4^-2 loses a single hydrogen ion in a reaction, it forms PO4^-3.
PO43-
H3PO4 (aq) + H2O (l) ---> 2H3O+ (aq) + PO4-3 (aq)donor acid + acceptor base ---> conjugate acid + conjugate basethe answer above is wrongto form a conjugate, the ion H2PO4 - must lose a hydrogen ion H+i.eH2PO4 - -H+ = HPO4 2-(conjugate base)
H3PO4 (aq) + H2O (l) ---> 2H3O+ (aq) + PO4-3 (aq)donor acid + acceptor base ---> conjugate acid + conjugate basethe answer above is wrongto form a conjugate, the ion H2PO4 - must lose a hydrogen ion H+i.eH2PO4 - -H+ = HPO4 2-(conjugate base)

Phosphate ion (PO4 3-) acts as a base in the Bronsted-Lowry acid-base theory by accepting a proton (H+).
'Conjugate' means ONE proton more (acid) or less (base) than the described acid or base respectively:So the conjugate acid of PO43- (phosphate) is HPO42- (monohydrogen phosphate)
Strong acids and bases dissociate completely in water. Strong acids produce a pH of less than 3 and form weak conjugate bases. Strong bases produce a pH greater than 10 and form a weak conjugate acid.
Yes, Na3PO4 (sodium phosphate) is a basic salt as it is composed of the sodium cation (Na+) and the phosphate anion (PO4^3-), which can accept protons from water to form hydroxide ions (OH-) and hence increase the pH of a solution.
The chemical formula for phosphate is PO4^3-.
