pH, ionization, acid dissociation.
29. The pH of a sample of rain is found to be 3.3. Calculate the percentage of HSO4- that is ionized in this sample, given that the acid dissociation constant for the second stage of ionization of H2SO4 is 1.2E-2.
PLease do this only if you are 100% positive you're right. My program is very picky and likes to tell me the answer's are wrong :( Thanks!
The solution (2 pages in length) shows how to seal with dissociation of acids that can contribute two protons, such as sulphuric acid.
The solution shows how not to fall into the common trap of assuming full dissociation right in the first reaction.
