Question

How much water should be added to 200 cc of seminormal solution to make it exactly decinormal

Answer 1

Dear Student,

Normality (N1) = 0.5 (seminormal)

Volume(V1) = 200 cc

Normality (N2) = 0.1 (decinormal)

​Volume (V2) = ?

(N1)​(V1) = ​(N2) ​(V2)

0.5 X 200 = 0.1 X ​(V2)

(V2) = 1000 ml

Volume of water added = 1000 -200 = 800 ml
