Question

You are given 1 L of 2 N H2SO4 and 1 L 5 N H2SO4. What will be the maximum volume of 1.5 M H2SOthat you can prepare from these two solutions?

Solution

Correct option is

1.5 L

 

Normality of resulting solution = 1.5 × 2 = 3.0

In order to prepare maximum volume of 3.0 N solution, concentrated solution (x L) be mixed with entire (=1L) of dilute solution.

 

Maximum volume of resulting solution = (1 + 0.5)L
