Question

15.
A 5 M solution of H, SO, is diluted from 1 litre to a volume of 100 litres, the normality of the solution wix
(1) 1N
(2) 5N
(3) 0.1N
(4) 0.5 N​

Answer 1

Explanation:

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 0.1N....
