WebDec 24, 2014 · When acetic acid is dissolved in water there is an equilibrium reaction: C H X 3 C O O H + H X 2 O ↽ − − ⇀ C H X 3 C O O X − + H X 3 O X + Since acetic acid is a weak acid, the equilibrium position lies well to the left, with only a small fraction of the acetic acid molecules reacting to form ethanoate and hydronium ions. Ethanol is a neutral molecule and the pH of a solution of ethanol in water is nearly 7.00. Ethanol can be quantitatively converted to its conjugate base, the ethoxide ion (CH 3 CH 2 O −), by reaction with an alkali metal such as sodium: 2 CH 3 CH 2 OH + 2 Na → 2 CH 3 CH 2 ONa + H 2. or a very strong base such as … See more Ethanol (abbr.
