Apparent Dissociation Constant of a Porphyrin
Maria Ballester and Victor Castro
The purpose of this laboratory is to determine the apparent acid dissociation constant, š¾a, by estimating the pš¾a value of a porphyrin using visible spectrophotometry. This apparent pš¾a value is measured by graphic interpolating the absorbance changes obtained at varied wavelengths for different acid concentrations using the HendersonāHasselbach equation.

Calculating Avogadro's Number
Maria Ballester and Victor Castro Ph.D.
The value of Avogadro's number is found by using kinetic theory along with (a) the volume change upon sublimation of a small quantity of dry ice (CO2), and (b) the diffusion length, as a function of time, of iodine in air at a certain temperature.
