Question

Hydrochloric acid solutions A and B have concentrations 0.5 N and 0.1 N respectively. The volumes of
solution A and solution B required to make a 2-litre solution of 0.2 N HCl are

Answer 1

Answer 2

Answer:

The normality equation is  

N 1   + V  1  +N 2  + V 2

=N 3  (V  1  +V  2)

Suppose the volume of A mixed is x.

Then the volume of B will be (2−x).

Applying normality equation,

N  1   V  1  +N  2 ​ V  2

​ =N  3  

(V 1  +V  2  )

0.5x+0.1(2−x)=0.2×2

0.5x+0.2−0.2x=0.4

x=0.5

So, volume of A will be 0.5 lit

Volume of B will be = 2−0.5 = 1.5 lit

Hence, the correct option is A
