Question

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?

Answer 1

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

Answer 2

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.
