Buffer's 7h
WebAug 10, 2024 · The strongest acids are at the bottom left, and the strongest bases are at the top right. The conjugate base of a strong acid is a very weak base, and, conversely, the conjugate acid of a strong base is a very weak acid. Example 7.7. 1. Identify the conjugate acid-base pairs in this equilibrium. CH 3 CO 2 H + H 2 O ↽ − − ⇀ H 3 O + + CH ... WebFor example, a buffer can be composed of dissolved HC 2 H 3 O 2 (a weak acid) and NaC 2 H 3 O 2 (the salt derived from that weak acid). Another example of a buffer is a solution containing NH 3 (a weak base) and NH 4 Cl (a salt derived from that weak base). Let us use an HC 2 H 3 O 2 /NaC 2 H 3 O 2 buffer to demonstrate how buffers work.
