Question

Milli equivalents of $HCl$ is $1$ L mixture is:

• A. $100$
• B. $200$
• C. $300$
• D. $235$

Answer 1

The correct option is A $100$

Milliequivalents of $H_{2}S{O}_4+$Milliequivalent of $HCl$ $=$Milliequivalents of $NaOH$ $=48\times \frac{1}{16}=3$
Milliequivalents of $H_{2}S{O}_4$ in $20$ mL mixture $=$ Milliequivalent of $BaS{O}_4=\frac{0.466}{\frac{233}{2}}\times 1000=4$
Milliequivalents of $H_{2}S{O}_4$ in $10$ mL mixture $=\frac{4}{2}=2$
Milliequivalents of $HCl$ in $10$ mL mixture $3-2=1$

Milliequivalents of $HCl$ in $1000$ mL mixture $\frac{1000}{10}\times 1=100$
