Question

The most concentrated solution among the following is
a) 1.0m H2SO4
b) 1.0N H2SO4
c) 2.0 % (w/v) H2SO4
d) 0.1m. H2SO4 ​

Answer 1

Answer:

We know that :

Normality=Molarity×Basicity

For sulphuric acid, the basicity is 2.

∴N

1

=0.1×2=0.2N

V

= ?

N

=0.1×1=0.1N

V

=40ml

0.2×V

=0.1×40

V

=20ml

Therefore, the option is C.
