Buffer Hermetica

I can never remember how the maths works with buffers and acids and bases and all that stuff. I never even learned the stuff about effective vs thermodynamic pKas. These are my notes on what i've remembered or learned. A lot of this is very basic.

Some common pKas (thanks Sigma and Petrik Laboratories):

AcidpKa (25 C)
Boric9.23, 12.74, 13.80
Phosphoric2.15, 7.20, 12.33
PIPES3.00, 6.76
