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 will be
(1) 1N
(2) 5N
(3) 0.1 N
(4) 0.5 ​

Answer 1

M1 = 5

V1 = 1L

n factor = 2

N1 = M1 x n factor = 5 x 2 = 10

V2 = 100L

The moles will be same in both the cases,

N1 X V1 = N2 X V2

10 X 1 = N2 X 100

N2 = 0.1

option 3) is correct
