Q. $25 \,mL$ 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

Solutions

Solution:

For $HCl , M=N=0.1$

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

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

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