    in a solution of 0.10 M H2SO4 , list these concentrations in order of the greatest to smallest: [H3O+], [OH-], [HSO4-], and [SO4(-2)]

    the answer showed that none of those concentrations is equal to others, but i got [HSO4-]=[SO4-2] (eventhough i'm not quite sure)

    could you help me out ?

    thanks alot

    [H<sub>3</sub>O<sup>+</sup>]
    [HSO<sub>4</sub><sup>-</sup>]
    [OH<sup>-</sup>]
    [SO<sub>4</sub><sup>2-</sup>]

    there is ur list, [H<sub>3</sub>O<sup>+</sup>] is greates and [SO<sub>4</sub><sup>2-</sup>] is least

    its quite simply, [H<sub>3</sub>O<sup>+</sup>] will instantly become 0.1 because [H<sub>2</sub>SO<sub>4</sub>] is a strong acid, aswell will [HSO<sub>4</sub><sup>-</sup>]. but some of this will protolyse again, so it will be a bit less than 0.1, when it protolyse [H<sub>3</sub>O<sup>+</sup>] will increase slightly, therefor be greater than any. and there is so littly protolysing in the second step so there will be just very ery littly of [SO<sub>4</sub><sup>2-</sup>] so therefor its more likly to have more [OH<sup>-</sup>]
