Please reply as soon as possible, I really need the answer urgently. How many grams of NaOH are required to completely neutralize 100ml of 1M solution of H2SO4?

  • Chemistry -

    Start with the equation for the reaction

    NaOH + H2SO4 -> Na2SO4 + H2O

    which you need to balance.

    Then from the equation how many moles of NaOH react with each mole of H2SO4?

    Calculate number of moles of H2SO4 used (M)
    M=0.1 x 1 M =

    How many moles of NaOH needed? (N)

    Calculate molecular mass of NaOH (MM)

    mass required = MM x N

  • Chemistry -

    Thanks for help,
    Just a bit of confusion,
    Upon balancing, he equation appears like this:

    2NaOH + H2SO4 --> Na2SO4 + 2H2O

    So it is clear that 2 moles of NaOH are needed to react each mole of H2SO4, then why use M = 0.1 x 1M = ?
    And what's 0.1 in this formula?

    Awaiting your reply.
