Determination of pKa James McDuffie ABSTRACT: In this lab‚ the pKa of unknown solution #4 was measured Introduction: This lab focused on the equilibrium constant‚ Ka. Ka is associated with chemical properties of acids. The equivalence point will be reached once the moles of OH- equal the moles of HA and once this point is reached‚ the PH changes very quickly.

If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different
