Question

0.67 mol of acetic acid are added to 1 litre of pure water with no discernible change in volume. Determine the equilibrium concentrations of acetic acid (CH3COOH), acetate ion (CH3COO–) and hydronium ion (H3O+).

Acetic acid is a weak acid that partially dissociated in water according to
equation B1-2, with an acid dissociation constant Ka = 1.66 x10-5:

Acetobacter also known as "mother of vinegar" is an acetic acid bacterium
which converts alcohol into acetic acid in the presence of oxygen, according
to equation B1-1. As such it behaves as a catalyst.
