Expert Answer:

At equivalence-
Meq space of space straight H subscript 2 SO subscript 4 equals space 0.1 cross times 50 equals 5 space meq
Meq space of space NaOH equals space 0.2 cross times 150 equals 30 space meq
If space resultant space solution space normality space is space straight N subscript straight R.
Normality space of space resultant space solution space would space be

straight N subscript straight R equals fraction numerator straight N subscript 2 straight V subscript 2 space minus space straight N subscript 1 straight V subscript 1 over denominator straight V subscript 1 plus straight V subscript 2 end fraction
straight N subscript straight R equals fraction numerator 30 minus 5 over denominator 150 plus 100 end fraction equals 25 over 250 equals straight N over 10 space
It space would space be space straight a space basic space solution.
