This is sometimes called an ICE table: x = [H 3 O + Now use the pH formula : pH = -log [H 3 O +] -pH = log [H 3 O +] = 4.88 [H 3 O + = 10 -4.88 = 1.32 x 10 -5 WebJul 12, 2014 · C H X 3 C O O H + O H X − ↽ − − ⇀ C H X 3 C O O X − + H X 2 O where the weak acid and conjugate base are respectively C H X 3 C O O H and C H X 3 C O O X −. My concern is that this equation above goes nearly to completion ( K = 1.8 × 10 9) so I don’t see how this can even be a buffer solution. If not, how do they get the values? pop industry
