When asked to name all of the ions and molecules present in a 0.1 mol L-1 solution of CH3COOH, why are there OH- ions present if the equation is
CH3COOH(aq) + H2O(l) --> CH3COO-(aq) + H3O+(aq) ?

The water ionizes in such a manner that the product of the concentrations of H3O+ ions and OH- ions is constant (at 25C, the product is equal to 1*10^-14.
