Hydrolysis of salts of weak acid-weak base

  1. Dec 21, 2013 #1
    I just came across the hydrolysis of the salts and the formula
    pH=7+1/2(pKa-pKb)
    What's bugging me about this is how can this be independent of Concentration?
    I mean if we dilute it why wont it affect the pH? That means that even a negligible amount of such a salt can affect the pH of a bucket of water? Also there is no assumption involved so please explain how exactly is this plausible, thanks.
