Conjugate base hpo4 2
4. An acid with a low pKa: A. is a weak acid B. is a strong acid C. has a weak conjugate base D. both B and C. Give the conjugate acid of S^ {2-}. Write it ignoring super and subscripts (so, HPO_4^ {2-} would be HPO42-). Determine the Ka of the weak acid HA whose conjugate base has K b = 2.9 x 10 8 .B. H3PO4 represents the conjugate acid of H2PO4-. Conjugate acids are produced by the addition of hydrogen ions to the compound. Hence option B is incorrect. C. The PO43- represents the conjugate base of HPO42-. Conjugate bases are produced by the removal of hydrogen ions from the compound and hence option C is correct.The conjugate base of HPO4 is PO43-

2023-10-07. Description. Hydrogenphosphate is a phosphate ion that is the conjugate base of dihydrogenphosphate. It has a role as a Saccharomyces cerevisiae metabolite and a cofactor. It is a divalent inorganic anion and a phosphate ion. It is a conjugate base of a dihydrogenphosphate.Phosphoric acid is the parent acid, i.e. H 3P O4. Remove a proton from this, we get, H 2P O− 4 as the conjugate base. Or rather phosphoric acid donates a proton to water to give H 3O+ and H 2P O− 4. And remove a proton from H 2P O− 4 to get H P O2− 4 as the conjugate base. In water that's about as far as you go.CH3COOH is the conjugate acid and CH3COO- is the conjugate base. F- and HF is a conjugate acid base pair. F- is the conjugate base and HF is the conjugate acid. c. HPO4 2- (aq) + H2O (l) --> H2PO4-(aq) + OH-(aq) HPO42- and H2PO4- is a conjugate acid base pair. HPO42- is the conjugate base and H2PO4- is the conjugate base. Jun 11, 2015 · Then, I suppose you use the HH H H -equation to figure out the rest. At pH = pka2 = 7.21 the concentration of [H2PO4 (-)] = [HPO4 (2-)] = 0.40 M. This is because we have added 3 mole equivalents of K2HPO4 to 50*0.2 = 10 mmole of phosphoric acid, i.e. we have reached a total concentration of phosphoric acid protolytes of (3*50*0.2 + 50*0.2)/50 ...
