Q12 Acid Base Buffer

Acid-base buffers are briefly explained, as well as the buffering effect. The main point of the screencast, however, is the pH value calculation in the buffer range. Furthermore, it is described how buffer systems are formed in titrations of weak acid with a strong base. Original: "Wolfgang Dukorn"
