When 100 ml of M/10 H2SO4 is mixed with 500ml of M/10 NaOH,then what is the nature of the resulting solution and the normality of the excess reactant left?

Answer:
 Gram equivalents of H2SO4 =
 
     straight N cross times straight V left parenthesis in space straight L right parenthesis
equals 1 fifth cross times 100 over 1000
equals 0.02

Gram space equivalent space of space NaOH
equals 1 over 10 cross times 500 over 1000 equals 0.05

So comma after space use space of space 0.02 eq space straight H subscript 2 SO subscript 4 comma
equivalent space left equals 0.05 minus 0.02
space space space space space space space space space space space space space space space space space space space space space space space equals 0.03 space space

So space normality space of space excess space reactant space left space is space equals fraction numerator gram space equivalent over denominator Volume space in space litre end fraction
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals fraction numerator 0.03 over denominator 0.6 end fraction
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space equals 0.05 space straight N
