Question

What volume of N/2 and N/5 H2SO4 must be mixed to prepare N/5 H2SO4 5L

Answer 1

Explanation:-n/2 h2 so4=v1 l

n/10 h2so4=v2l

v1+v2=5-----------1

normality equation

n1 v1 +n2 v2 = n(v1+v2)

= 1/2,v1+1/10,v2=(1/5*5)

=v1/2+v2/10=1

sv1+v2=10

4v1+(v1+v2)=10

4v1+5=10

v1=5/9=1.25

v2=(s-5/4)l 15/4=3.75

1.25l of n/2 li2so4 and 3.75l of n/10 h2so4 must be mixed to prepare sl of n/s h2so4
