Question

How to dilute .1 normalty sulphuric acid into .02normalty sulphuric acid?

Answer 1

Answer:

By law of dilution,

M1V1 = M2V2

I.e. the product of molarity before dilition and the volume is equal to the product of molarity after dilution and the new volume.

So,

M2= 0.5×1÷10

= 0.05 M

Now normality

= molarity × n factor

= 0.05 × 2

=0.1 N
