Question

A 5 molar solution of H2SO4 is diluted from 1 liter to a volume of 10 liters, the normality

Answer 1

Known:

M₁=5M

a₁=H₂SO₄⇒H₂ =2

V₁=1 L

V₂=1000 L

Asked: N₂?

Answer:

Use dilution formula:

M₁.a₁.V₁=M₂.a₂.V₂

and

Remember that the normality of formula: N=M.a

So ,

5.2.1=100.N 

 10   =100N

 10   = N

 100

 0,1  =N

So,the normality is 0,1 N.
