WebDec 10, 2024 · HClO2 is a stronger acid than HBrO2. Doesn't the fact that Cl and Br are in the same group and the Br-O bond is longer and weaker than the Cl-O bond outweigh the greater electronegativity of the Cl bond though?

WebAcids and bases in the Brnsted model therefore exist as conjugate pairs whose formulas are related by the gain or loss of a hydrogen ion. Our use of the symbols HA and A - for a conjugate acid-base pair does not mean that all acids are neutral molecules or that all bases are negative ions.

Therefore, the "H"-"Cl" bond is weakened more from more uneven sharing of electrons, and weaker bond = stronger acidity. ... bristol evening post ukWeb(For a list of common weak acids and bases, see Table 8-2 in Oxtoby)8-2 in Oxtoby) teadm miniWebAcid HA A-Ka pKa Acid Strength Conjugate Base Strength Hydroiodic HI I-Hydrobromic HBr Br-Perchloric HClO4 ClO4-Hydrochloric HCl Cl-Chloric HClO3 ClO3-Sulfuric (1) H2SO4 HSO4-Nitric HNO3 NO3-Strong acids completely dissociate in aq solution (Ka > 1, pKa < 1).
