Playing Around with “Kaleidagraph” Program for Determination of pKa Values of Mono, Di and Tri Basic Acids in a Physical-Organic Chemistry Laboratory
pKa Kaleidagraph Acid-Base Equilibriums
2013/2/19
A simple and easy laboratory protocol for the determination of the pKa of mono, di and tri-basic weak acids is described in this paper by using arbitrarily simulated data as a function of pH. An equat...
