Is ethanoic acid a WEAK acid or a STRONG acid? Give a reason for
the answer.
(2)
7.1.2
An ethanoic acid solution has a pH of 3,85 at 25 °C. Calculate the
concentration of the hydronium ions, H3O+(aq), in the
solution.
(3)
Sodium ethanoate, CH3COONa(aq), forms when ethanoic acid reacts
with sodium hydroxide.
