I have to do much of the chemistry in the first few chapters everyday in my day job. Thank you for the clear explainations.
I also have to deal with phosphate buffers and reducing alkalinity with strong acids. When you have to to the math the mole is your friend. If you find a need to do this yourself read a highschool chemistry textbook. You can skip the bonding chapters if they bore you. But you can calculate any additions and removals quite easily once you have a little practice.
Also, thank you for the pK for NH3 and NH4+. I'll put that into a spread sheet.
