Question

20 mL of 10 N HCl are mixed with 10 mL of 36 N H 2 SO 4 and the mixture is made 1 L . Normality of the mixture will be (A) 0.56 N (B) 0.50 N (C) 0.40 N (D) 0.35 N

Tardigrade Admin · Accepted Answer

For H C l For H 2 SO 4 V1=20 mL V2=10 mL N1=10 N N2=36 N ∴ Normality of resulting mixture (N)=(N1 V1+N2 V2/V1+V2) =(10 N × 20+36 N × 10/20+10) =(200 N+360 N/30) =(560 N/30)=18.67 N ∴ The mixture is made one litre, therefore the normality of this solution is N1 V1=N2 V2 ∴ 18.67 × 30=N2 × 1000 N2 (18.67 × 30/1000)=0.56 N
