Question

how many ml of 0.1 molar H2SO4 must be added to 50 ml of 0.1 molar NaOH to give solution that has concentration 0.5 molar H2SO4

Answer 1

Answer:

When H

2

SO

4

is mixed with NaOH then neutralization reaction takes place,

and we have formula

N

1

V

1

−N

2

V

2

=N(V+V

2

)

normality = molarity× n-factor

n-factor for H

2

SO

4

= 2

let volume of H

2

SO

4

= x ml

so, putting the values we have

2×0.1×x−50×0.1=0.05(x+50)

on solving the equation we get,

x=100ml

so, millilitres of H

2

SO

4

added is 100 ml.
