It is H2PO4 - For acetic acid, CH3COOH, it is CH3COO-For H2PO4-, it is HPO4(2-) For HPO4(2-), it is PO3(3-) As you see, the conjugate base has just one proton less than the parent acid. In other words, a conjugate acid is the acid member, HX, of a pair of compounds that differ from each other by gain or loss of a proton. Expert Answer 100% (7 ratings) Previous question Next question Get more help from Chegg. the extent of dissociation of the dissolved acid or base. This problem has been solved! HNO3* NH+4(aq) conjugate acid* NH3(aq) base* H2PO−4(aq) conjugate acid H2PO−4(aq) conjugate base* H3PO4(aq) base H3PO4(aq) acid* NH+4(aq) conjugate base. Which of the following is the strongest acid? A conjugate acid, within the Brønsted–Lowry acid–base theory, is a chemical compound formed when an acid donates a proton (H +) to a base—in other words, it is a base with a hydrogen ion added to it, as in the reverse reaction it loses a hydrogen ion. H The classification of an acid or a base as weak or strong is determined by. The conjugate acid of any species, is that species plus a proton; so it's H_2PO_4^(-). This preview shows page 2 - 7 out of 8 pages.. 10. The Conjugate Acid Of PO3−4; Question: The Conjugate Acid Of PO3−4. See the answer. A conjugate base is the name given to the species that remains after the acid has donated its proton. On the other hand, a conjugate base is what is left over after an acid has donated a proton during a chemical reaction. H 3 PO 4 3. H 3 PO 4-2. 1. The conjugate base can accept a proton. In H2O the conjugate base is H2PO4-, being conjugated to the acid H3PO4. When we add a proton, we must conserve both mass and charge, we add H^+ to HPO_4^(2-) so the conjugate acid is simply H_2PO_4^(-). What is the conjugate base of H 2 PO 4-? The conjugate acid of PO3−4. Phosphoric acid there is 3 hydrogen atoms 1 phosphorous and 4 oxygen the hydrogen has a charge of 1 and the phosphate (PO4) has a charge of 3- so it will look like H- PO4 3- Get 1:1 help now from expert Chemistry tutors Check Answer and Solution for above question from Chemistry in Equilibrium - As well: H3PO4 is conjugated acid to the base H2PO4-. The conjugate base of HPO2-4 is (A) PO3-4 (B) H2PO-4 (C) H3PO4 (D) H3PO3. Determine whether each pair is a conjugate acid base pair CO2-/3, HCl PO3-/4 HPO2-/4 HI,I HCHO2, So2-/4 (the slashes are subscripts ) Question Asked May 3, 2020 Balance the reaction of KOH + H3PO4 = K3PO4 + H2O using this chemical equation balancer! TABLE OF CONJUGATE ACID-BASE PAIRS Acid Base K a (25 oC) HClO 4 ClO 4 – H 2 SO 4 HSO 4 – HCl Cl– HNO 3 NO 3 – H 3 O + H 2 O H 2 CrO 4 HCrO 4 – 1.8 x 10–1 H 2 C 2 O 4 (oxalic acid) HC 2 O 4 – 5.90 x 10–2 [H 2 SO 3] = SO 2 (aq) + H2 O HSO A conjugate acid can release or donate a proton. Use Bronsted Lowry Acid/Base Theory to identify conjugate acid base pairs. More free chemistry help at www.chemistnate.com What is the conjugate acid of H_2PO_4^(-)? See also here.
