Página 52 - The pH, or poH, curve is symmetrical with reference to the equivalence-point, but this is not the case in the titration of a weak acid with a strong base, or of a weak base with a strong acid. In the former case the equivalence-point is on the alkaline side, and in the latter it lies in the acid region.
Página 25 - N solution of a salt of a weak acid and a strong base if the ionization constant for the acid is lO'4, lO'6, and 10"10. (b) Repeat the calculation of (a) for a 0.01 N solution. 6.107 Calculate the pH at 25...

Página 101 - Eq. (4-22) that the weaker the acid and the higher its concentration, the higher the equivalence point pH. In the titration of a weak base with a strong acid, the pH at various points can be determined in a fashion similar to that for a weak acid. It should be obvious, however, that such a titration is the mirror image of the acid titration and that the equations for the acid titration are applicable if pOH is substituted for pH and if...
Página 25 - A neutralization reaction might occur when an acidic solution of an organic salt (a solution of a salt of a strong acid and a weak base) is mixed with a basic solution (a solution of a salt of a weak acid and a strong base).
