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.
