MCQ

The normality of $H _{2} SO _{4}$ in the solution obtained on mixing $100 mL$ of $0.1\,M H _{2} SO _{4}$ with $50 mL$ of $0.1$ $M\,NaOH$ is $\times 10^{-1}\,N$. (Nearest Integer)

Answer

Correct option: A.

$1$

a
No. of equivalents of $H _{2} SO _{4}=100 \times 0.1 \times 2=20$

No. of equivalents of $NaOH =50 \times 0.1=5$

No. of equivalents of $H _{2} SO _{4}$ left $=20-5=15$

$150 \times x =15$

$x =\frac{1}{10}=0.1 N =1 \times 10^{-1}\,N$
