Question

1 mole of H2SO4 will exactly neutralize

Answer 1

you didn't mention option by which alkaline we have to neutralise the acidic solution of H2SO4.

generally, NaOH is used to neutralise it. I am going to elaborate with this.

first find normality of H2SO4.

we know, normality = n - factor × molarity

n - factor of H2SO4 = 2

and molarity of H2SO4 solution if volume of solution is taken 1L, = 1M

so, normality = 2 × 1 = 2N

as we know, for exact neutralisation,

normality of acid = normality of base.

so, normality of base should be 2N

if volume of NaOH is also taken as 1L

now, normality = 2N = n - factor × molarity

or, 2 = 1 × number of moles of NaOH/1L

or, number of moles of NaOH = 2mol

hence, 1 mole of H2SO4 will exactly neutralize with 2 moles of NaOH.
