Question

20ml of 10N HCL are dilluted with distilled water to
form one litre of the solution. What is the normality
Do the dillute solution ?​

Answer 1

Answer:

N1VI=N2V2

10*10=0.1v

v=1000 ml

Thus we need to add (1000-10)=990 ml of water to get decinormal solution

Answer 2

Answer:

N1 = 20

V1 = 10ml = 0.01L

V2 = 250ml = 0.25L

The no. of moles will be taken same in both the cases,

N1 X V1 = N2 X V2

20 X 0.01 = N2 X 0.25

N2 = 0.8

option d) is correct
