Question

25 mL of a solution of barium hydroxide on titration with a 0.1 molar solution of hydrochloric acid gave a liter value of 35 mL. The molarity of barium hydroxide solution was (A) 0.35 (B) 0.14 (C) 0.28 (D) 0.07

Tardigrade Admin · Accepted Answer

For HCl , M=N=0.1 N1 V1+N2 V2 ; 25 × N1=0.1 × 35 N1=(0.1 × 35/25) ; ∴ M=(0.1 × 35/25 × 2)=0.07

Q. $25 m L$ of a solution of barium hydroxide on titration with a $0.1$ molar solution of hydrochloric acid gave a liter value of $35 m L$ . The molarity of barium hydroxide solution was

0.35

0.14

0.28

0.07

For $H Cl, M = N = 0.1$

$N_{1} V_{1} + N_{2} V_{2}; 25 \times N_{1} = 0.1 \times 35$

$N_{1} = \frac{0.1 \times 35}{25}$ ;

$∴ M = \frac{0.1 \times 35}{25 \times 2} = 0.07$
