The undissociated base (B) is present in the greatest concentration, with the products being present in relatively smaller amounts in this equilibrium mixture. How would this affect the magnitude of Kb? Do you expect it to be small or large? Which is the strongest base? Name of base Ammonia (NH3) Methylamine (CH3NH2) Ethylamine (C2HSNH2) Diethylamine (C2Hs)2NH Pyridine (CsHsN) Kb value 1.76 x 105 Why? 4.4 x 104 5.6 x 104 Which is the weakest base? 1.3 x 10-3 1.7 x 109 Why? The larger the Kb the. (stronger/weaker) the base. Since a weak base dissociates incompletely setting up an equilibrium, what method could you think of that you could use to determine the concentration of (OH"] ions given the initial concentration of the acid and its Kb?
