Question

$100$ mL each of $\frac{N}{2}$ $NaOH$, $\frac{N}{5}$ $HCl$ and $\frac{N}{10}$ $H_{2}S{O}_4$ are mixed together. The resulting solution will be :

• A. acidic
• B. neutral
• C. alkaline
• D. none of these

Answer 1

Answer: (C)

alkaline

Given,
Meq. of $NaOH=\frac{1}{2}\times 100=50$
Meq. of $HCl=\frac{1}{5}\times 100=20$
Meq. of $H_{2}S{O}_4=\frac{1}{10}\times 100=10$;
Total Meq. of acid $=20+10=30$
Total Meq. of $NaOH=50$
So, $30$ Meq. of acid and base reacts with each other and forms salt, so remaining amount is $=50-30=20$
So, resulting solution will be alkaline.
