Chemistry Buffers

  1. May 4, 2005 #1
    hi guys need some help with buffers heh

    anyways my query is say i have a buffer system, then i add say a strong base or a strong acid, then the ph changes, whats a general statement i can make for these observations regarding the h+ ion concentration and stuff. I know that if i have the buffer, and i add hcl the h+ ions will be consumed by the conjugate base in the buffer and if we add heaps of acid the ph will decrease cos of too much h+ just an opinion anyone care to help me out :)

    and anyone also care to give me reasons and differences why ka value experimentally is different to the literally value? when doing a titration of Nh3 against HCl. thanks

    i posted here since i realise this would be most appropriate as it is the chemistry forun :)
