For the definitions of Kan constants scroll down the page. Is it because it wont dissociate to form either a base or an acid? Rated by 1 million+ students Get app now Login. The boiling point of the solvent above a solution will be greater than the boiling point of the pure solvent whether the solution contains a non-volatile solute or a volatile solute. Because strong acids are essentially 100% ionized, the concentration of the acid in the denominator is nearly zero and theKavalue approaches infinity. The Kb value for ammonia is 1.8 x 10 a. O What's something you just don't understand? Weak acids with relatively higherKavalues are stronger than acids with relatively lowerKavalues.

Screen capture done with Camtasia Studio 4.0. = 141.98 g/mol) that has been dissolved in a 250 mL volumetric flask and diluted to the mark. The acid ionization represents the fraction of the original acid that has been ionized in solution. Polyprotic acids are those with more than one acidic proton. More. -3.7^@"C" Your strategy here will be to determine the van't Hoff factor for sodium iodide, "NaI" calculate the molality of the solution calculate the freezing-point depression of the solution The idea is that the freezing point of a solution is lower than the freezing point of the pure solvent, which for water is 0^@"C" at normal pressure. While TSP is not toxic per se, it is severely irritating to gastric mucosa unless used as part of a buffered solution. Disclaimer - accuracy of the values shown, especially for the strong acids, is questionable.
