25 ml of a solution containing HCl and H 2 SO 4 required 10 ml of a 1 N NaOH solution for neutralization. 20 ml of the same acid mixture on being treated with an excess of AgNO 3 gives 0.1435 g

Question

25 ml of a solution containing HCl and H 2 ​ SO 4 ​ required 10 ml of a 1 N NaOH solution for neutralization. 20 ml of the same acid mixture on being treated with an excess of AgNO 3 ​ gives 0.1435 g of AgCl . The normality of the HCl and the normality of the H 2 ​ SO 4 ​ are respectively

TestHub · Accepted Answer

Meq. HCl + Meq. H₂SO₄ = Meq. of NaOH N 1 ​ × 25 + N 2 ​ × 25 = 10 × 1 HCl + AgNO₃ ⟶ AgCl + HNO₃ 20 × N 1 ​ excess 0.1435 g Meq. of HCl = Meq. of AgCl 20 × N 1 ​ = 143.5 0.1435 × 1000 ​ N 1 ​ = 20 1 ​ = 0.05 N N 2 ​ = 25 10 − 1.25 ​ = 0.35 N
