PLEASE!!! But we occasionally come across a strong acid or base, such as stomach acid, that has a strongly acidic pH of 12. So pKa is equal to 9.25. [ ClO ] [ HClO ] = So ph is equal to the pKa.

Addition of chlorine to water gives both hydrochloric acid (HCl) and hypochlorous acid (HClO): Cl2 + H2O ⇌ HClO + HCl Cl2 + 4 OH ⇌ 2 ClO + 2 H2O + 2 e Cl2 + 2 e ⇌ 2 Cl When acids are added to aqueous salts of hypochlorous acid (such as sodium hypochlorite in commercial bleach solution), the resultant reaction is driven to the left, and chlorine gas is formed. Thus, the formation of stable hypochlorite bleaches is facilitated by dissolving chlorine gas into … WebHCl HBr HI HClO 4 TfOH Gas phase GA values (kcal mol-1) G3MP2 328.2 318.6 293.2 292.4 G4MP2 329.2 318.6 294.2 292.5 G4 329.3 318.1 293.5 291.8 CBS-QB3 326.8 318.4 292.1 290.8 ... hydrobromic acid pKa in water, hydroiodic acid pKa in water, perchloric acid pKa in water and trifluoromethanesulfonis acid pKa in water HCl pKa in DMSO, HBr pKa …
Pauling's second rule is that the value of the first pKa for acids of the formula XOm(OH)n depends primarily on the number of oxo groups m, and is approximately independent of the number of hydroxy groups n, and also of the central atom X. Approximate values of pKa are 8 for m = 0, 2 for m = 1, −3 for m = 2 and < −10 for m = 3. Alternatively, various numerical formulas have been … WebApr 3, 2024 · HClO− (aq) + H2O(l) ⇌ HClO(aq) +OH− (aq) So right from the start, you should expect the pH of the solution to be > 7 because of the presence of the hypochlorite anions. Now, the base dissociation constant of the hypochlorite anions is calculated using the equation Kb = [HClO] ⋅ [OH−] [ClO−]
WebFeb 2, 2024 · In general, for titrations of strong acids with strong bases (and vice versa), any indicator with a pK in between about 4.0 and 10.0 will do. For the titration of a weak acid, however, the pH at the equivalence point is greater than 7.0, so an indicator such as phenolphthalein or thymol blue, with pKin > 7.0, should be used.
