Question

What will be the normality of a solution obtained by mixing 100 mL 0.1 N HCl and 200 mL 0.25 N HNO3 ?
 
  1. 0.2 N
  2. 0.52 N
  3. 0.50 N
  4. 0.10 N


Solution

The correct option is A 0.2 N
Formula to calculate the normality of  the solution after mixing is 

N1V1+N2V2=N3V3

N1 of HCl=0.1 NV1 of HCl=100 mL
N2 of HNO3=0.25 NV2 of HNO3=200 mL

N3​ and V3​ are the normality & volume of the final solution.
V3=Total volume=100+200=300  mL
(0.1×100)+(0.25×200)=N3×(300)60=N3×300N3=0.2 N
 The normality of the solution obtained is 0.2 N.
