Webb30 juni 2024 · Answer: a. the pH is only determined by the concentration of B and no titrant is added to the solution yet. b. when acid is added to the weak base B it is converted to conjugal acid BH+. WebbA base will give hydroxide ions in reaction with water. B (aq) + H2O (l) → HB+ (aq) + OH- (aq) From the pH we know pOH = 14 - 9.82 = 4.18. We can calculate now [OH-]. The [HB+] equals [OK-]. The actual concentration [B] = 0.1 - [HB+]. This three concentrations must be substituted in the equation of Kb to calculate the value of Kb. 9 Pete Gannett
