  1. Even in concentrated aqueous solutions, water is the most prevalent species. Each NaBr formula unit produces one Na ion and one Br– ion. Thus, [Na ] = [Br–] = 0.10 M. Na and Br– are neutral, meaning they do not affect the concentrations of H3O or OH–.
    Thus, the amounts of H3O and OH– are dictated by the Kw for water. [H3O ] = [OH–] = 1.0× 10–7 M
    NaBr is soluble and dissociates completely, which means there are zero NaBr units present.
