Note that ammonia and most organic bases release OH- ions due to hydrolysis, not dissociation. Again the answer is Kw/Ka (HNO3), and since Ka (HNO3) is taken as around infinity if HNO3 is a strong acid, then this Kb is (around) 0. You can create your own Flashcards and upload decks Rated by 1 million+ students Get app now Login. Experimentally, we know that the change in boiling point of the solvent above a solution from that of the pure solvent is directly proportional to the molal concentration of the solute: T is the change in boiling point of the solvent, Kb and Ka are also related through the ion constant for water, Kw, by the relationship Kw = Kb x Kb=a. Use table search to locate desired compound in database. Not exactly infinity, huh. Kb is related to the acid dissociation constant, Ka, by the simple relationship pKa + pKb = 14, where pKb and pKa are the negative logarithms of Kb and Ka, respectively. The ionization for a general weak acid, HA, can be written as follows: Because the acid is weak, an equilibrium expression can be written. We can calculate its basic dissociation constant (Kb) using the following expression. Given the acid constant for a weak acid . The (aq) shows that they are aqueous dissolved in water.The equation for Na3PO4 ( Sodium phosphate and H2O sometimes isnt considered a chemical reaction since it is easy to change the Na + and PO4 3- back to Na3PO4 (just let the H2O evaporate). A lower pKb value indicates a stronger base. Acids with a pKa value of less than about -2 are said to be strong acids.
